The motor ship sailed 60 km along the river in 1 1/3 hours. the speed of the river flow is 2 2/3 km / hour.

The motor ship sailed 60 km along the river in 1 1/3 hours. the speed of the river flow is 2 2/3 km / hour. which way the motor ship will make in 2, 4 hours against the river flow.

It is known that the ship sailed 60 kilometers along the river in 1 1/3 hours.
Let’s find the speed of the ship in the river downstream.
60/1 1/3 = 60/4/3 = 60 * 3/4 = 45 km / h.
The speed of the river is 2 2/3 km / h.
Let’s find our own speed of the ship.
45 – 2 2/3 = 42 1/3 km / h.
Let’s find the speed of the ship in the river against the current.
42 1/3 – 2 2/3 = 39 2/3 km / h.
Let’s find which way the motor ship will make in 2.4 hours at the current speed.
39 2/3 * 2.4 = 119/3 * 24/10 = 2856/30 = 95.2 kilometers.
