A thrill ride at an amusement park travels 55 miles per hour. To the nearest hundredth, how many feet per second is this?

The first thing you should know are the following conversions:

1mi = 5280 feet

1h = 3600 s

Applying the conversions we have

(55) (miles / hour) (1/3600) (h / s) (5280/1) (feet / mi) = 80.67feet / s

answer

this is 80.67feet / s
