Answer 2

Question :-

If Sonam runs at a speed of 25km/hr, how long will she take to run a 800 meter race?​

Given,

Sonam runs at the speed of $25km/hr$.

To Find,

Time taken by Sonam to cover 800 m.

Thus,

(1) Make the units same

1 m = $\frac{1}{1000}$ $km$ $=0.001km$

800 m = $\frac{8 }{1000}$ $km$ $=0.8km$

$Time=\frac{Distance}{Speed}$

(Substitute the variables with actual values.)

$?=\frac{0.8 }{25}$

$=\frac{0.8}{25}$ × $\frac{4}{4}$

$=\frac{3.2}{100}$

$=0.032$

Hence, Sonam takes $0.032 hrs$ to complete a 800 m race.

$1hr=60min$

$0.032hr=0.032$ × $60min$

$=1.92min$

Therefore,

Sonam takes $1.92$ $minutes$ or $0.032$ $hours$ to complete a race of 800 m.
