A military convoy travels at an average speed of 45 miles per hour. If they need to cover a distance of 360 miles, how many hours will the journey take?
- A6 hours
- B9 hours
- C7 hours
- D8 hours
Show answer & explanationAnswer & explanation
Correct answer: D. 8 hours
To find the time, divide the total distance by the average speed. Time = Distance / Speed = 360 miles / 45 mph = 8 hours.
Why the other options are wrong
- A. This is incorrect; 360 divided by 45 is not 6.
- B. This is incorrect; 360 divided by 45 is not 9.
- C. This is incorrect; 360 divided by 45 is not 7.
Time Calculation (D-R-T)
Determining the duration of a journey or process given the distance covered and the rate of travel (speed).
- Formula: Time = Distance / Rate (Speed).
- Units must be consistent (e.g., miles and miles per hour).
Memory trick: Time is distance over speed, a journey's true deed.
