A rock has a diameter of .5 miles. If you walk around it at a rate of 2 miles per hour, how long will it take you to walk all the way around the rock? Use 3.14 as pi.
Solve for radius:
C = 2(3.14)r
C = 2(3.14)(0.5/2)
C = 1.57-miles
Solve question asked:
(1.57 miles) / (2 miles/hour)
0.785-hours or 47-minutes and 6-seconds
Great answer isiber17 :)
That is one BIG rock LOL
