Question

A car cover a cartain distance in 50 minutes if it runs at 45 km per hr. How much time will it take to cover the same distance at a speed 30km per hour

Answer 1

Step-by-step explanation:

Speed = 45 km/hr

Distance Speed x Time =

=> 45 x 50 / 60

=> 37.5 km

Now,

In the second case:

Distance = 37.5 km

Speed = 30 km/hr

Time = Distance / Speed

=> 37.5 / 30

We can directly convert the time in minutes from hours by multiplying by 60. We will do this 50 simplify our calculation.

=> 37.5 x 60 / 30

=> 75 minutes.

Hope it helps!! :)
