if a cheetah can run 60 mph.how fast can it run in feet per second.

Using dimensional analysis, we have

60mph x 1 hr / 3600 sec x 5280ft / 1 mile  = 88 ft/s

Just type in 60 mph to feet per second into google and it should give you the answer.

There are 5280 feet in each mile.

There are 60 seconds in each minute and 60 minutes in each hour so there are 3600 seconds in each hour.

(60 miles / hour) x (5280 feet / 1 mile) x (1 hour / 3600 seconds) 

=  (60 x 5280 feet) / (3600 seconds)  =  88 feet / second
