Speed of the boat downstream of the river 22 km / h and against the current of 18 km h find a) speed of the river flow b) own speed of the boat
1) Let us find out what is the speed of the river, if it is known that the boat moves along the river at a speed of 22 km / h, and against the river, its speed is 18 km / h.
(22 – 18) / 2 = 2 km / h.
2) We find out what own speed the boat develops, if it is known that along the river its speed is 22 km / h, and the speed of the river flow is 2 km / h.
22 – 2 = 20 km / h.
Answer: the speed of the river flow was 2 km / h, and the boat’s own speed was 20 km / h.
