The motor ship covered 144 km in 8 hours and the boat in 9 hours, by how much the speed of the motor ship is higher than the speed of the boat.
The problem is solved in 3 steps.
In the first step of the task, you need to find the speed of the ship:
1) 144: 8 = 18 (km / h) – speed of the ship.
In the second, you need to find the speed of the boat:
2) 144: 9 = 16 (km / h) – boat speed.
In the third step, you need to find out how much the speed of the ship is greater than the speed of the boat:
3) 18 – 16 = 2 (km / h)
Answer: at 2 km / h.
