The boat, whose own speed is 14.8 km / h, went 3 hours downstream and 4 hours upstream

The boat, whose own speed is 14.8 km / h, went 3 hours downstream and 4 hours upstream. What path has the boat made during all this time, if the current speed is 2.3 km / h.

Let’s find the distance that the given boat has traveled along the river, for this we need the indicated value of the own speed of the given boat, add the indicated value of the speed of the river, and the result. which we get, multiplied by the time that the boat given to us spent on the path along the river:

(14.8 + 2.3) * 3 = 51.3 km – this is the distance that the boat given to us has traveled along the river;

Let’s find the distance that the given boat has traveled against the stream of the river, for this we need the indicated value of the own speed of this boat, subtract the indicated value of the speed of the current of the river, and the result that we get is multiplied by the time that the boat given to us spent traveling against the course of the river:

(14.8 – 2.3) * 4 = 50 km – this is the distance that the boat given to us has traveled against the stream of the river;

Let’s find all the distance that the boat given to us has covered for the entire time, for this we need to add up the found distances that the boat given to us passed along the river and against the river:

51.3 + 50 = 101.3 km is the entire distance that the boat has covered.
