Question

If a man walks six feet per second, how many minutes will it take for to
walk 5400 feet?

Answer 1

`\large \bf \implies{15 \:minutes}`

Explanation:

In this question speed remain same

`\bf \longrightarrow{Apply \: (d_1)/(d_2) = (t_1)/(t_2) }`

`\bf \longrightarrow{(6)/(5400) = (1)/(t_2) }`

`\bf \longrightarrow{t_2 = 900 \: second}`

Convert this second into minutes

`\bf \longrightarrow{1min = 60sec} \\ \bf \longrightarrow{1sec = (1)/(60) min} \\ \bf \longrightarrow{ (900)/(60) = 15min}`

Therefore, A man take 15 minutes to walk 5400 feet.
