What is the distance in miles of a trip that takes 9 hours at an average speed of 15 miles per hour?
| 240 miles | |
| 40 miles | |
| 135 miles | |
| 540 miles |
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 distance:
distance = \( \text{speed} \times \text{time} \)
distance = \( 15mph \times 9h \)
