Question

Kiran is driving a car at a speed of $48\mathrm{km}/\mathrm{hr}$. How much distance will she cover in $1sec$?

Answer 1

Assumptions:

$1km/h=\frac{5}{18}m/s$

Step 1: Given Data:

Speed of car driven by Kiran$=48km/h=\frac{5}{18}\times 48m/s=\frac{40}{3}m/s$

Time taken by a car to cover this distance, $1sec$

Step 2: Calculation of Distance:

As we know speed is distance covered in per unit time so,

$$\begin{gathered} Speed=\frac{Dis\tan ce}{time}\Rightarrow dis\tan ce=speed\times timetaken \\ Dis\tan ce=\frac{40}{3}m/s\times 1sec=13.3m \end{gathered}$$

Hence, distance covered in one minute,$13.3m$
