Accepted Answer

The ability to analyze numerical information and solve problems logically

Answer

Quantitative reasoning is the ability to interpret, analyze, and apply numerical information to solve problems in various contexts. It involves using mathematical concepts and logical thinking to make sense of data, identify patterns, and draw conclusions. This skill is vital for decision-making and understanding the world around us.

Question 2

If a train travels 60 miles in 1.5 hours, what is its average speed?

Accepted Answer

45 miles per hour

Answer

To calculate average speed, you divide the total distance by the total time. In this problem, the distance is 60 miles and the time is 1.5 hours. Dividing 60 by 1.5 yields 40 miles per hour. Therefore, 40 miles per hour is the correct average speed for the train.

Question 3

What is the next number in the pattern: 2, 4, 8, 16, ...?

Accepted Answer

32

Answer

This pattern is a geometric progression where each number is obtained by multiplying the previous number by 2. Starting with 2, the sequence is 2 (x2) = 4, 4 (x2) = 8, 8 (x2) = 16. Following this rule, the next number would be 16 multiplied by 2, which equals 32.

Question 4

What is 25% of 120?

Accepted Answer

30

Answer

To find 25% of a number, you can convert the percentage to a fraction (25% = 1/4) or a decimal (25% = 0.25). Then, multiply this value by the given number. Calculating 1/4 of 120, or 0.25 multiplied by 120, both result in 30.

Question 5

A container holds 2 liters of water. How many milliliters is this?

Accepted Answer

2,000 mL

Answer

This question tests knowledge of metric unit conversions. There are 1,000 milliliters (mL) in 1 liter (L). Therefore, to convert 2 liters to milliliters, you multiply 2 by 1,000, which gives 2,000 mL.
