Answer 2

Correct Question :

A girl covers a distance of 5 km in 20 min by car. Find the velocity of the car in km/hr.

Solution :

Here..

• Distance = 5 km.

• Time = 20 min

We have to find the velocity of the car.

We know that,

Velocity = $\dfrac{Distance}{Time}$

Before putting values in above formula. First convert, minute into hours.

Time = 20 min.

To convert 20 min into hours, divide it by 60.

Time = $\dfrac{20}{60}$

=> 0.33 hrs.

Now,

We have time = 0.33 hrs and distance = 5 km.

Put them in above formula to find velocity of the car.

Velocity = $\dfrac{5}{0.33}$

Velocity = 15.15 km/hr.

15.15 km/hr is the velocity of the car.
