Solution

First, let's find out the total distance covered by the motorboat.

The formula to calculate distance is speed * time.

Given, speed = 45 kmph and time = 10 hours

So, distance = 45 kmph * 10 hours = 450 km

Now, we need to find out the speed required to cover the same distance in 15 hours.

We rearrange the formula to find speed = distance / time

So, speed = 450 km / 15 hours = 30 kmph

Therefore, to cover the same distance in 15 hours, the motorboat must travel at the speed of 30 kmph.

So, the correct answer is B) 30 kmph.
