How long does it take harry to go 0.7 miles if he can run 1.2 miles in 6 minutes

Harry will take 21 seconds

Explanation:

Speed = distance covered / time taken

Harry covers 12 miles in 6 minutes so,

the speed of Harry will be 12/6 = 2 miles per minute.

Therefore, if he covers 0.7 miles then time taken by him will be,

Time taken = distance covered / speed

                   = 0.7 / 2

                   = 0.35 minutes

                   = 0.35 x 60 seconds

                   = 21 seconds

I hope this helps :)
