Question

A bus is moving at a speed of $84km/hr$. How much distance will it cover in $1min45sec$?

Answer 1

Given that,

Speed = $84km/hr$

Time = $1min45sec=60+45=105sec$.

$=\frac{105}{60\times 60}hr(Sinceconvertingsecintohours)$

Distance =?

$Dis\tan ce=Time\times Speed$

$$\begin{gathered} Dis\tan ce=84\times \frac{105}{3600} \\ =\frac{8820}{3600} \\ =2km450m \end{gathered}$$

Therefore, the distance is $2km450m$.
