The motor boat’s own speed is 23 km / h. The speed of the river is 4 km / h. How far does a motorboat travel upstream of a river in 3 hours?
Before determining the distance that the boat will travel against the course of the river in a specified time, you need to find its speed in this direction.
23 – 4 = 19 km / h.
Thus, the traversed path will be:
3 * 19 = 57 km.
Equation solution:
3 * (23 – 4) = 69 – 12 = 57 km.
Answer: The boat will cover 57 kilometers.
