Express the rate 10ft/sec in miles/hr

6.82 miles/hr to the nearest hundredth.

Step-by-step explanation:

There are 5280 feet in a mile so to convert to miles per second we divide by 5280.

10 ft / sec = (10/5280) miles / sec

There are 3600 seconds in an hour so to convert to miles / hour we multiply by 3600:-

Answer = (10 * 3600) / 5280

= 6.82 miles/hr (to the nearest hundredth)
