Raju is moving in his car with a velocity of $50\ km/h$. How much distance will he cover in 5 minutes?

Here, velocity of the car $v=50\ km/h=50\times\frac{5}{18}=\frac{125}{9}\ m/s$

Time $t=5\ minutes=5\times60=300\ second$

Therefore, distance traveled by car $s=velocity\times time$

$=v\times t$

$=\frac{125}{9}\times300$

$=4166.67\ m$

$=\frac{4166.67}{1000}\ km$

$=4.2\ km$
