(y2)5If a car travels 40 miles in 2 hours, what is the average speed?
| 25 mph | |
| 20 mph | |
| 60 mph | |
| 75 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)What is the distance in miles of a trip that takes 2 hours at an average speed of 60 miles per hour?
| 225 miles | |
| 75 miles | |
| 120 miles | |
| 275 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 = \( 60mph \times 2h \)
120 miles
