Question

A man covers a total distance of $750\mathrm{km}$ in his car with an average speed of $50\mathrm{km}/\mathrm{hr}$. How much time does he take?

Answer 1

Step 1: Given Data:

Distance covered by man $=750km$

Average speed of man,$=50\mathrm{km}/\mathrm{hr}$

Step 2: To calculate time taken by man:

As we know average speed is ratio of total distance covered with total time taken so mathematically:

$$\begin{gathered} Averagespeed=\frac{Totaldis\tan ce}{totaltime}\Rightarrow totaltime=\frac{Totaldis\tan ce}{Averagespeed} \\ totaltime=\frac{750km}{50km/h}=15hour \end{gathered}$$

Hence,time taken,$=15hour$
