Question

A cyclist covers a distance of 3 km in 5 minutes, what is the speed of the cyclist? Please make it simple and not complicated. Please give the answer in km/h

Answer 1

Answer:36km/h

Explanation:We know 1h= 60min and 1min=1/60h so 5mins=5/60h=1/12h

Also speed=distance/time=3÷1/12=3×12=36km/h

Answer 2

$\small{\underline{\sf{\orange{Given:\rightarrow}}}}$

$\sf{Distance = 3 km}$

$\sf{Time=5min}$

$\small{\underline{\sf{\red{Find:\rightarrow}}}}$

$\sf{Speed \ of \ cyclist?}$

$\small{\underline{\sf{\blue{SoLution:\rightarrow}}}}$

Firstly change min to hr,

$\sf{5 min = 0.083hr}$

Formula used for finding speed=

$\boxed{\sf{S=\dfrac{d}{t}}}$

where s= speed, d= distance, t= time

putting value of d and t in formula we get,

$\sf{s= \dfrac{3}{0.083}}$

$\boxed{\sf{s=36km/h}}${approx}

$\sf{\underline{ \therefore speed \ of \ cyclist = 36km/h}}$
