The speed of the motor boat is 3 times the speed of the boat at the oars. How long does it take for a motor boat to cover 24 km, if a boat with oars can cover this distance in 6 hours? How far will a motorboat cover in 5 hours?

1. To solve the problem, let us find the speed at which the boat was paddling per hour, if it is known that it sailed 24 kilometers in 6 hours.

24/6 = 4 kilometers.

2. Let us find the speed of the motor boat, if it is said that its speed is 3 times greater than the speed of the boat on the oars.

4 * 3 = 12 kilometers.

3. Let’s determine how long the motor boat will take 24 kilometers.

24/12 = 2 hours.

4. Find out the distance that a motor boat will pass in 5 hours, if it is known that it was going at a speed of 12 kilometers per hour.

5 * 12 = 60 kilometers.

Answer: A motor boat will cover 24 kilometers in 2 hours, and in 5 hours it will cover 60 kilometers.
