how lond does it take harry to go 0.7 miles if he can run 12 miles in 6 minutes

Answers

Answer:

Harry will take 21 seconds.

Explanation:

Speed of Harry = [tex]\frac{\text{Distance covered}}{\text{Time taken}}[/tex]

Since, Harry covers 12 miles in 6 minutes,

Then the speed of Harry = [tex]\frac{12}{6}[/tex]

                                          = 2 miles per minute

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

Time taken = [tex]\frac{\text{Distance covered}}{\text{Speed}}[/tex]

                   = [tex]\frac{0.7}{2}[/tex]

                   = 0.35 minutes

                   ≈ 0.35 × 60 seconds

                   = 21 seconds
