Question 436700: I am trying to figure out how to show work for converting speed feet per second into miles per hour. The question is:
The speed of sound is 1,088 feet per second. Convert the speed of sound to miles per hour. Round your answer to the nearest whole number.
I have never learned how to convert this and there is no example in the book. Can you help please.

The speed of sound is 1,088 feet per second.
Convert the speed of sound to miles per hour.
-------------------
1088(ft/sec)[(1mi/5280ft)/(3600sec/1 hr)]
-----
= [1088*1*3600]/[1*5280*1](miles/hr)
----
= (3916800/5280)(mi/hr)
---
= 741.82 mph
