The speed of the river flow is 2.3 km.h The boat’s own speed is 14.5 km, h.

The speed of the river flow is 2.3 km.h The boat’s own speed is 14.5 km, h. What way did the boat sail along the river in 4 hours?

The speed of the boat downstream will be equal to the sum of its own speed and the speed of the current:

1) 14.5 + 2.3 = 16.8 (km / h) – speed of the boat downstream.

S = V * T, – where S is distance, V is speed, and T is time.

Using this formula, we find the path that the boat covered in 4 hours:

2) 16.8 * 4 = 67.2 (km) – the distance covered by the boat in 4 hours.

Answer: in 4 hours the boat sailed 67.2 km downstream.
