Two small airplanes started out at the same time from two cities 1,470 kilometers apart and met in 3 hours. If the rate of one was 230 kph, what was the average speed
of the other?
-----------------------------------------------------------------------
The first airplane covered the distance of 230 * 3 hours = 690 km from the starting point to the meeting point.
Hence, the second airplane covered 1470 km - 690 km = 780 km.
Therefore, the average speed of the second airplane was = 260 .
Answer. The average speed of the second airplane was 260 kilometers per hour.
