Answer:
Here walking speed is 3.5 miles per hour
Step-by-step 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
