Answer 1

$\Huge\mathbb{\blue{QUESTION -}}$

How many km per hour does a man walk who passes through a street 600m long in 5 minutes.

$\Huge\mathbb{\blue{SOLUTION-}}$

Man walks through street 600m long

In km :-

$\implies{\sf \dfrac{600}{1000}}$

$\implies{\sf 0.6km}$

Time taken by man to pass through street is 5 min

In hours

$\implies{\sf \dfrac{5}{60}}$

$\implies{\sf 0.083\:hours}$

In km/h

$\implies{\sf \dfrac{0.6}{0.083}}$

$\implies{\bf 7.22\:km/h}$

$\Huge\mathbb{\blue{ANSWER-}}$

${\bf \red{7.22\:km/h}}$ man walk who passes through a street 600m long in 5 minutes

Answer 2

Answer:

The conventional approach to this question would be to find the velocity in metres per second, and then convert it to kilometres per hour.But the easiest approach is more simple:Distance = 600m = 0.6kmTime = 5min = (5/60)hrs = (1/12)hrsSpeed = Distance/Time = (0.6)/(1/12) = 12(0.6) = 7.2kmph
