Two boats simultaneously departed from the pier in the opposite direction. The speed of the first boat is 25 km / h.

Two boats simultaneously departed from the pier in the opposite direction. The speed of the first boat is 25 km / h. At what distance will they be from another in 4 hours, if the second boat traveled 48 km in 2 hours?

Since the second boat covered 48 km in 2 hours, its speed is:

48: 2 = 24 km / h.

Since the boats were moving in different directions, the removal speed is equal to the sum of their speeds:

24 + 25 = 49 km / h.

Then after 4 hours the distance will be:

49 * 4 = 196 km.

Answer: the distance between the boats is 196 km.
