Two motor boats departed from the two piers at the same time towards each other and met after 9 hours. The speed of the first boat is 30 km / h, the speed of the second is 45 km / h. What is the distance between the marinas?

1. Since, according to the condition of the problem, the boats are moving towards each other, therefore they become closer, that is, they come closer. Let’s find the speed with which these boats are approaching, if it is known that the speed of one of them is 30 km per hour, and the speed of the second boat is 45 k per hour.

30 + 45 = 75 km per hour.

2. Since the boats were on the way before the meeting at 9 o’clock, we can calculate the distance that was between them initially.

75 * 9 = 675 km.

Answer: The distance between the marinas is 675 km.
