The motor ship went 2.5 hours along the river and 3.2 hours against the current. What is the general route of the motor ship

The motor ship went 2.5 hours along the river and 3.2 hours against the current. What is the general route of the motor ship if its own speed is 22 km / h and the current speed is 3 km / h?

The solution of the problem:
We calculate how far the motor ship traveled along the river, taking into account that the speed of the motor ship is equal to its own speed plus the speed of the current:
(S = V * t),
(22 + 3) * 2.5 = 62.5 (km),
We calculate the distance traveled by the motor ship, upstream:
(22 – 3) * 3.2 = 60.8 (km),
We find the general route of the ship:
62.5 + 60.8 = 123.3 (km).
Answer: the total route of the ship is 123.3 km.
