Find the speed of the boat downstream if the boat’s own speed is 12 1/2 km / h and the speed of the river is 2 1/4 km / h

When the boat moves with the current, the force of the current adds up with the speed of the boat, forcing it to swim faster. So the speed of the boat downstream will be:
12 1/2 + 2 1/4 = 12 + 1/2 + 2 + 1/4 = 14 + 2/4 + 1/4 = 14 3/4 = 14.75 km / h.
Answer: the speed of the boat downstream will be 14 3/4 km / h or 14.75 km / h.
