In 2017, there were about 13,500 deadly automobile accidents. About 4,018 were a result of drunk driving accidents. Approximately what percent of the deadly automobile accidents were a result of drunk driving?
Explanation:
To find the percentage of deadly automobile accidents caused by drunk driving, we divide the number of drunk driving accidents by the total number of deadly automobile accidents and multiply by 100. (4018 / 13500) * 100 = 0.2979 * 100 ≈ 29.79%. Rounded to the nearest whole number, it is approximately 30%. Therefore, about 30% of the deadly automobile accidents in 2017 were a result of drunk driving.

Identify the type of error that is found in the following sentence:
Sometimes the difference between being a good firefighter and an average firefighter comes down to weather or not the firefighter is properly trained.
Explanation:
The error in the sentence is the misspelling of "weather" as "weather." This mistake affects the spelling of the word, making option A the correct choice - "weather" is misspelled. It should be "whether."
A patient has been instructed by a doctor that the maximum dosage of medication is 3 1/2 tables for every 50 pounds of weight. If the patient weighs 200 pounds, what is the maximum number of tablets he/she should take per dose?
Explanation:
To find the maximum number of tablets the patient should take per dose, we need to calculate based on the dosage instruction given. For every 50 pounds of weight, the patient can take 3 1/2 tablets. Since the patient weighs 200 pounds, we divide 200 by 50 to find how many sets of 3 1/2 tablets are needed: 200 ÷ 50 = 4 sets. Then, we multiply the number of sets by the number of tablets per set: 4 sets × 3 1/2 tablets = 14 tablets.
A fire station receives a structure fire alarm call on July 18th at 2:22 AM. An automobile accident alarm call comes in on July 18th at 4:50 AM and another structure fire alarm call on July 19th at 3:27 PM. How much time has elapsed from the first structure fire alarm call to the second structure fire alarm call?
Explanation:
To find the elapsed time between the two structure fire alarm calls, we subtract the time of the first call from the time of the second call. The first call occurred on July 18th at 2:22 AM, and the second call occurred on July 19th at 3:27 PM. Converting both times to a 24-hour clock format, we have 2:22 AM and 15:27.
The time difference is 13 hours and 5 minutes for the same day (July 18th), and then an additional 24 hours from July 18th, 15:27 to July 19th, 15:27. Thus, the total elapsed time is 13 hours and 5 minutes + 24 hours = 37 hours and 5 minutes.
A group of four firefighters purchase groceries at the store. The cost of the items is as follows: $9.65, $3.25, $11.60, $5.85, and $7.50. In order for the bill to be equally split, approximately how much does each firefighter owe (not including tax, rounded up to the nearest whole dollar)?
Explanation:
To split the total bill equally among four firefighters, you sum the cost of all items and divide by four. Adding the prices: $9.65 + $3.25 + $11.60 + $5.85 + $7.50 = $38.85. Dividing $38.85 by 4 yields $9.7125. Rounding up to the nearest whole dollar, each firefighter owes approximately $10. This question tests the cognitive ability to perform basic arithmetic calculations, essential for various tasks in firefighting, such as budgeting, resource allocation, and equipment maintenance.
You are in an elevator with a weight capacity of 1,650 pounds. There are five other people in the elevator with you. One person weighs 192, one person weighs 116, and the other two each weigh 156 pounds. Assuming that you weigh 173 pounds, how much additional weight could the elevator hold before exceeding capacity?
Explanation:
To determine the additional weight the elevator can hold, we first calculate the current total weight in the elevator. The weight of the people already in the elevator is 192 + 116 + 156 + 156 + 173 = 793 pounds. Subtracting this total from the elevator's weight capacity (1650 - 793) gives us 857 pounds of available capacity. Therefore, the elevator can hold an additional 857 pounds before exceeding its weight limit.
Be _______of your surroundings and try to ______ dangerous situations.
Explanation:
This question evaluates the candidate's cognitive ability by testing their understanding of vocabulary and their ability to apply appropriate terms in a given context. "Cognizant" means being aware or conscious of something, and "mitigate" means to lessen or reduce the severity of something.
What is the minimum number of rope sections a firefighter would need to rope off a danger zone that is 28 feet long by 40 feet wide assuming that each rope section comes in 50-foot sections?
Explanation:
To rope off the danger zone, the firefighter would need to use ropes along the length and width of the area. Since each rope section comes in 50-foot sections, they can cover 50 feet in length or width. To cover a 28-foot long and 40-foot wide area, the firefighter would need at least 3 rope sections: two sections along the length (2 * 50 = 100 feet) and one section along the width (1 * 50 = 50 feet), totaling 150 feet.
If a fire engine is traveling 45 mph for 18 minutes, how far will it travel? (Distance = Rate X Time)?
Explanation:
To find the distance traveled, we multiply the rate (speed) by the time. 45 mph * (18 minutes / 60 minutes per hour) = 45 mph * 0.3 hours = 13.50 miles. Therefore, the fire engine will travel 13.50 miles in 18 minutes at a speed of 45 mph. This question assesses cognitive ability in performing basic mathematical calculations, which is essential for firefighters to make quick and accurate assessments in various emergency situations.
