Question

Mr. and Mrs. Chin flew from New York

to Tokyo, which is a distance of 6375
miles. If it took the plane 15 hours to
fly from New York to Tokyo, what was
the plane's average speed per hour?

Answer 1

425 miles per hour

Explanation:

Find the speed per hour by dividing the distance by the number of hours:

6375/15

= 425

This means the plane traveled 425 miles in one hour.

So, the plane's average speed was 425 miles per hour
