Question

1. The speed of a planet's moon in orbit is about 29500

feet per second. How many miles per hour does the
planet's moon travel?

Answer 1

20,114 mi/h

Explanation:

It can be convenient to remember that 1 mi/h = 22/15 ft/s. To convert the given number to the appropriate units, we can divide by this conversion factor:

(29500 ft/s)/((22/15 ft/s)/(1 mi/h)) = (29500·15/22) mi/h = 20113 7/11 mi/h

≈ 20,114 mi/h
