The speed of the boat along the river is 15 km / h and the speed of the river is 2.7 km / h, calculate the speed of the boat against the river.
To solve this problem, you first need to determine the speed of the boat when moving against the stream of the river.
To do this, it is necessary to subtract the speed of the river from its own speed.
In this case, we get.
15 – 2.7 = 12.3 km / h. Speed of the boat against the current of the river.
In this case, in order to determine the speed of the boat along the river, it will be necessary to do the opposite, namely to add the speed of the river to the boat’s own speed.
In this case, we get.
15 + 2.7 = 17.7 km / h. Speed of the boat along the river.
