A military supply truck travels 240 miles in 4 hours. If it maintains the same speed, how far will it travel in 7 hours?
- A480 miles
- B420 miles
- C520 miles
- D360 miles
Show answer & explanationAnswer & explanation
Correct answer: B. 420 miles
First, calculate the speed of the truck: 240 miles / 4 hours = 60 miles per hour. Then, multiply this speed by the new time: 60 mph * 7 hours = 420 miles.
Why the other options are wrong
- A. This would be the distance if the speed was 68.5 mph.
- C. This would be the distance if the speed was approximately 74.2 mph.
- D. This would be the distance if the speed was 51.4 mph.
Distance, Rate, Time
The relationship between distance, an object's speed (rate), and the time it travels, often expressed as Distance = Rate × Time.
- Rate = Distance / Time
- Time = Distance / Rate
- Units must be consistent (e.g., miles and hours).
Memory trick: Speedy Truck's Journey: Rate times Time gets the miles.
