Question

A man runs at a speed if 10km/h how much time will he take to cover 750 meters​

Answer 1

Answer:

Time = Distance / speed

= 750 m / (10 × 5/18 m/s)

= 270 seconds

Time taken to cover 750 m is 270 seconds

Answer 2

Given:

A man runs at the speed of 10km/h

To find:

The time in which he covers 750 metres

Explanation:

$\sf speed\: of \:man,S=10 kmh{}^{-1}=10×\dfrac{5}{18}=\dfrac{50}{18}ms{}{-1}$

$\sf distance\: travelled,D=750 m$

$\sf time,t=?$

we know that

$\boxed{\sf Speed=\dfrac{Distance}{time}}$

substituting the values

$\longrightarrow \sf \dfrac{50}{18}=\dfrac{750}{t}$

$\longrightarrow \sf \dfrac{1}{18}=\dfrac{15}{t} \\ \\ \longrightarrow \sf t=15×18$

$\boxed{\sf t=270 seconds}$
