40 yd in 5 seconds. How many feet per hour is this?

1yd=3ft

First find how many yards per hour

2,200yds per hour

Then multiple by 3

6,600 feet per hour

40 yards in 5 seconds would be

8 yards in 1 second

To convert to yards per hour multiply by 3,600

8 * 3,600 = 28,800 yards per hour

and to convert to feet per hour, multiply by 3

3 * 28,800 =

86,400 feet per hour
