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 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.
