From one village to another on the river you can sail by boat in 1.5 hours. How long will it take for a motor boat to take this route if the speed of the boat is 3 km / h and the speed of the boat is 13.5 km / h.

1. Let’s calculate the distance from one settlement to another by multiplying the boat’s speed by the time it takes it to sail this way:
1.5 * 3 = 4.5 km.
2. Let’s calculate how long it will take a boat to cover this path, dividing this path by the speed of the boat:
4.5 / 13.5 = 45/135 = 9/23 hours.
Answer: a motor boat will cover the distance from one village to another in 9/23 hours.
