How many feet per second is 90 mph?

Answer 1

There are 5,280 feet in a mile. So 90 miles per hour is 475,200 feet per hour. (90 x 5280)

475,200 divided by the 60 minutes in the hour comes out to 7920 feet per minute. Dividing 7920 feet per minute by the sixty seconds in a minute comes to 132 feet per second.

This is also, if you are interested, 44 yards per second. (132 feet per second divided by three feet in a yard)
