how much time will it take a car to travel 60 kilometers if the car is traveling at an average speed of 40km/hr?

lbvjy [14]

In the question, we are given with speed of a car and the distance it have to travel.

Given:

Speed of the car = 40 km/hr.
Distance to travel = 60 km

So, we can say that in 1 hour, the car can travel 40 km. And we have to find the time taken by the car to travel 60 km.

This can be easily done by using the Speed, Distance and Time formula which says:

$\large{ \boxed{ \bf{Distance = Speed \times Time}}}$

So, let's solve by using this formula.

⇛ s = v × t

⇛ 60 km = 40 km/hr × t

⇛ t = 60 km / 40 km/hr

⇛ t = 3/2 hr.

⇛ t = 90 mins or 1 1/2 hours

So, time the car will take to travel 60 km:

$\large{ \boxed{ \bf{ \purple{t = 1 \dfrac{1}{2} hr}}}}$

And we are done !!
