Question

Maria runs 10 miles every day. If she doubles her usual speed, she can run the 10 miles in one hour less than her usual time. What is her usual speed?

Answer 1

Her usual speed is 5 miles an hour.

Explanation:

Since it takes one hour for her to run ten miles that means she is running at 10 miles an hour. So if you divide that by 2 it would be five.

Have a nice and great day.
