Free MRAB Route Planning Questions and Answers — Questions and Answers
Question 1: You have the following stops to make: 123 Elm St, 789 Maple Ave, 456 Oak St, 321 Pine Rd. If all roads are straight and there are no traffic lights, <br>which sequence minimizes the total distance traveled?
- Elm St → Oak St → Maple Ave → Pine Rd
- Maple Ave → Oak St → Elm St → Pine Rd
- Pine Rd → Elm St → Oak St → Maple Ave
- Elm St → Maple Ave → Oak St → Pine Rd (Correct answer)
Correct answer: Elm St → Maple Ave → Oak St → Pine Rd
Route optimization aims to minimize driving time by planning the most efficient path. Option A suggests a direct progression from the starting point (Main St) through each street in a logical sequence (Park St, Lake St, Hill St, River Rd). Without a map or specific travel times, this linear progression is generally the most efficient strategy to avoid detours and backtracking, thus minimizing overall driving time.
Question 2: Your starting point is at 100 Main St. You need to visit the following addresses: 200 Park St, 300 Lake St, 400 Hill St, 500 River Rd. <br>Which route should you take to minimize driving time?
- Main St → Park St → Lake St → Hill St → River Rd (Correct answer)
- Main St → Lake St → River Rd → Hill St → Park St
- Main St → River Rd → Hill St → Park St → Lake St
- Main St → Hill St → Park St → Lake St → River Rd
Correct answer: Main St → Park St → Lake St → Hill St → River Rd
Effective route planning involves considering external factors like traffic conditions. Since 5th Avenue experiences heavy traffic between 8:00 AM and 9:00 AM, the most efficient strategy is to avoid it during that peak time. By visiting 7th Ave and 6th Ave first, the meter reader can then proceed to 5th Ave after 9:00 AM when traffic is expected to have subsided, minimizing delays and optimizing the route.
Question 3: You know that traffic is heavy on 5th Avenue between 8:00 AM and 9:00 AM.<br> If you have stops at 10 5th Ave, 20 6th Ave, and 30 7th Ave, how should you plan your route?
- Start with 5th Ave before 8:00 AM, then 6th Ave, and end with 7th Ave.
- Start with 7th Ave, then 6th Ave, and end with 5th Ave after 9:00 AM. (Correct answer)
- Start with 6th Ave, then 5th Ave, and end with 7th Ave.
- Avoid 5th Ave entirely and rearrange the schedule.
Correct answer: Start with 7th Ave, then 6th Ave, and end with 5th Ave after 9:00 AM.
When a specific stop has a time-sensitive deadline, it becomes the priority in route planning. Since Elm St requires a reading by 10:00 AM, the meter reader must visit Elm St first to ensure this deadline is met. After completing the time-sensitive stop, the remaining stops (Maple St and Oak St) can then be visited in any convenient order, with a logical progression often being the most efficient.
Question 4: You have to complete three meter readings, with one stop requiring a reading by 10:00 AM. The stops are at 100 Elm St, 200 Maple St, and 300 Oak St.<br> Which route should you take if Elm St requires the reading by 10:00 AM?
- Maple St → Oak St → Elm St
- Elm St → Maple St → Oak St (Correct answer)
- Oak St → Maple St → Elm St
- Elm St → Oak St → Maple St
Correct answer: Elm St → Maple St → Oak St
Route optimization requires balancing proximity with known obstacles. Starting with Oak St, which is closest, is efficient. Since Elm St is under construction and slower, it should be scheduled later in the route to minimize its impact on overall travel time. Visiting Maple St next and saving the slower Elm St for last allows for a more efficient flow, reducing the cumulative delay caused by the construction.
Question 5: You know that Elm St is under construction, making it slower to travel. You need to visit Elm St, Oak St, and Maple St. <br>Which route should you take if Oak St is the closest to your start point?
- Oak St → Maple St → Elm St (Correct answer)
- Elm St → Oak St → Maple St
- Maple St → Oak St → Elm St
- Oak St → Elm St → Maple St
Correct answer: Oak St → Maple St → Elm St
To determine the total number of meters read, you sum the meters completed in the morning and the afternoon. If the combined total of meters read was 193, it represents the sum of the two parts of the day's work. This is a basic addition problem to determine the overall productivity.
