| The speed of the boat is 7.85 km h, the speed of the current is 2.6 km h, how long it will take to sail along the river a distance of 12.54 km.
The boat speed along the river will be the sum of the boat’s own speed and the current speed:
7.85 + 2.6 = 10.45 km / h.
To find out how long it takes a boat to sail a certain distance at a given speed, the distance must be divided by the speed of the boat:
12.54: 10.45 = 1.2 hours.
Answer: the boat will sail 12.45 km along the river in 1.2 hours.
