In order to find the boat’s own speed, it is necessary to calculate the difference between the speed of the boat downstream and the speed of the river.
V = 14 3/7 – 2 1/4, where V is the boat’s own speed.
We bring the fractions to a common denominator and calculate the speed of the boat:
V = 14 3/7 – 2 1/4 = 14 12/28 – 2 7/28 = 12 5/28 (km / h).
Answer: the boat’s own speed is 12 5/28 km / h.
