Question

If a man walks 10 miles in 2 hours and then 2 miles in the next 2 hours, what was his average speed?​

Answer 1

3mph

Explanation:

Speed = distance/time

10 miles in 2 hours is equal to 5mph. (10 divided by 2)

2 miles in 2 hours is equal to 1mph. (2 divided by 2)

To find an average, add the number and divide by the number of groups.

5 + 1 = 6.

6 divided by 2 = 3.

This makes his average speed 3mph.
