The boat sailed on the lake for 0.3 hours then against the river flow for 1.2 hours Find the path covered by the boat if the boat’s own speed is 40.2 km / h and the river speed is 2.3 km / h.

1) How many kilometers did the boat sail on the lake? To find the distance traveled, you need to multiply the speed by time.

40.2 * 0.3 = 12.06 (km)

2) What is the speed of the boat when moving against the stream of the river? When moving against the current, the boat’s own speed will decrease by the amount of the river’s current speed.

40.2 – 2.3 = 37.9 (km / h)

3) How many kilometers did the boat sail upstream of the river?

37.9 * 1.2 = 45.48 (km)

4) What is the distance traveled by the boat on the lake and against the river?

12.06 + 45.54 = 57.54 (km)

Answer. 57.54 km.
