Find the speed of the boat, sailing with the river and against the current, if its own speed is 1/12 km / min, and the speed of the river is 1/100 km / min.

In order to find the speed of the boat along the river, you need to add the speed of the river to the boat’s own speed. In order to find the speed of the boat against the current of the river, you need to subtract the speed of the river from the boat’s own speed. Then 1) 1/12 + 1/100 = 50/600 + 6/600 = 56/600 = 7/75 kilometers per minute – the speed of the boat along the river. 2) 1/12 – 1/100 = 50/600 – 6/60 = 44/600 = 11/150 kilometers per minute – boat speed against the river.

Answer: 7/75 and 11/150 kilometers per minute.
