Answer:

Here walking speed is 3.5 miles per hour

Explanation:

Here, we want to calculate the average speed in miles per hour

mathematically, we know that;

speed = distance/time

from the question, the distance is 7/10 miles

The time is 1/5 hour

Thus we have;

Speed = 7/10 divided by 1/5

speed = 7/10 * 5/1 = 7/2 = 3.5 miles per hour
