The acceleration due to gravity is 32.2 ft/s^2 . Find the acceleration due to gravity in km/(hr·min).

Can someone please help me solve this? Thank you!

That is a weird unit conversion problem! convert ft to km, and one of the s (in the denominator) to hr and the other s to min.

I presume you know that there are 60 minutes in an hour and 60 seconds in a minute so 60(60)= 3600 seconds in an hour. "hr-min" is a peculiar way of expressing "per second per second" but is possible. 1 "second per second" is (1/3600 hr)(1/60 min)= 1/216000 hr-min. Do you know that there are 5280 feet in a mile and that there are approximately 0.61 miles per kilometer.
