Explanation:
The body travels 1 mile in 10 mins. First we have to calculate speed in miles/hour. We know speed is total distance covered divided by total time.
Speed of the body in miles/hr:


1 mile equals to 5280 feet. We have to find the speed of the body in feet/s. 10 mins = 10 × 60 secs = 600 s.
Speed of the body in feet/s:


Speed of the body is 60 miles/hr and 8.8 ft/s.
