Two boats departed from the pier simultaneously in opposite directions. The speed of one is 25 km / h, the other is 35 km / h. Make up expressions for calculating the distance between the boats and calculate how many kilometers will be between them in 1 hour, in 2 hours, in 3 hours? “

The solution of the problem:

1. In order to find out the distance of the boats in 1 hour, it is necessary to add up the speed of each of them. Thus, we will calculate the distance at which they will move away from each other every hour.

25 + 35 = 60 km.

2. In order to find out how far the boats will move away in a few hours, it is necessary to multiply the sum of their speeds by the number of hours that will be on the way of the boat. Therefore, in 3 hours the distance between them will be equal to:

(25 + 35) * 2 = 120 km.

3. The distance in 3 hours will be equal to:

(25 + 35) * 3 = 180 km.

Answer: The distance between the boats will be 60, 120 and 180 km, respectively.
