A motor ship and a boat departed from one pier in one direction. The speed of the ship is 47 km / h, the speed of the boat is 56 km / h. What is the distance between them in 5 hours?

Method 1.

1. Since the boat and the motor ship move in the same direction at different speeds, we find the speed of their removal:

56 – 47 = 9 km / h.

2. Let’s answer the question of the problem:

9 * 5 = 45 km.

Answer: 45 km.

Method 2.

1. Find out the distance that the boat will cover in 5 hours:

5 * 56 = 280 km.

2. Find out the distance that the motor ship will pass in 5 hours:

5 * 47 = 235 km.

3. Let’s answer the question of the problem:

280 – 235 = 45 km.

Answer: 45 km.
