How many hours does it take a car to travel 35 miles at an average speed of 35 miles per hour?
| 8 hours | |
| 1 hour | |
| 5 hours | |
| 9 hours |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for time:
time = \( \frac{\text{distance}}{\text{speed}} \)
time = \( \frac{35mi}{35mph} \)
