Question

On a trip to the grand canyon, you drove 168 miles in 3 1/2 hours. what was your average speed

Answer 1

The average speed can be calculated by taking the ratio of distance and time. That is:

average speed = distance / time

average speed = 168 miles / (3.5 hours)

average speed = 48 miles / hour

Hence the average speed is 48 miles per hour.
