Two boats sailed simultaneously from the same pier in opposite directions, one at 35 km / h and the other at 45 km / h.

Two boats sailed simultaneously from the same pier in opposite directions, one at 35 km / h and the other at 45 km / h. What is the distance between them in 1.5 hours?

1. Find out how many kilometers the first boat will sail in an hour and a half if it moves at a speed of 35 kilometers per hour:

35 * 1.5 = 52.5 (km).

2. Let’s determine how many kilometers the second boat will sail in an hour and a half if it moves at a speed of 45 kilometers per hour:

45 * 1.5 = 67.5 (km).

3. Let’s find what the distance will be between the first and the second boat in an hour and a half after sailing, if the first swam 52.5 kilometers, and the second 67.5 kilometers:

52.5 + 67.5 = 120 (km).

Answer: there will be 120 kilometers between the boats.
