The speed of the motor boat downstream is 37 km / h, the speed of the river is 3 km / h. How far does a motor boat sail against the current in 2 hours?
1. Let us determine the value of the boat’s own speed, subtracting from its speed downstream the speed with which the river carries it:
37 – 3 = 34 km / h.
2. Now we can find out the speed of the boat sailing against the current, reducing its own speed by the speed of the current, we get:
34 – 3 = 31 km / h.
Answer: against the current, the boat picks up a speed of 31 km / h.
