Two boats sailed from the pier in opposite directions. After 4 hours, the distance between them was 292 km. The average speed of one boat was 3 km / h. What was the average speed of the other boat?
The solution of the problem:
After 4 hours, according to the condition, there was a distance of 292 km between the ships, which means that the speed of their distance is equal to:
292: 4 = 73 (km / h) – the speed of the distance between the two boats.
Boats move in opposite directions, which means that the speed of their distance is the sum of their speeds, that is:
73 – 3 = 70 (km / h) – speed of the second boat.
Answer: The second boat was moving at a speed of 70 km / h.
