A car travels 200 km in 4 hours. How long will it take to travel 500 km?

Given:  A car travels 200 km in 4 hours.

To do: Find how much time it will take for the car to  travel 500km

Solution:

$Speed  =  \frac{Distance}{ Time}$

$Speed = \frac{200}{4}   =  50$

Speed of car = $50$ km / hr

Which means car can cover 50 km in 1 hr.

$Time \ taken    =  \frac{Distance}{speed}$

Time taken   to cover 500 km  =  $\frac{500}{50}$  =  $10$

Time = $10$ hr

So, it can cover $500$ km in $10$ hr
