Physics news on Phys.org
I find it convenient to know that 60 mph=88 f/s,
and 50 mph=80 km/h.

First you need to know how many feet are in a mile.
I looked up that a foot is 1/3 of a yard and a mile is 1760 yards, so there are 3*1760=5280 feet in a mile (God, I hate these units)

Then you can just write:
1 [mile/hour] = 1 [5280 ft/3600 seconds]=5280/3600 ft/s=22/15 ft/s.

EDIT: There are 3600s in an hour. duh.

You should learn about significant figures.
