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
