Solution

First, let's find out the distance covered by the car moving at a speed of 75 km/hr in 2 hours.

Distance = Speed x Time Distance = 75 km/hr x 2 hr = 150 km

Now, if the speed of the car is reduced by 15 km/hr, the new speed of the car is 75 km/hr - 15 km/hr = 60 km/hr.

To find out the time it will take to cover the same distance at the reduced speed, we can use the formula:

Time = Distance / Speed Time = 150 km / 60 km/hr = 2.5 hours

Since 1 hour is 60 minutes, 2.5 hours is 2.5 x 60 = 150 minutes.

So, the answer is B) 150 minutes.
