Question

Two trains leave towns 976km apart at the same time and travel toward each other. one train travels 22 /kmh slower than the other. if they meet in 4 hours, what is the rate of each train?

Answer 1

Let s be the slow train, and s+22 be the faster one. Then:
976/s+s+22=4
976=8s+88
8s=888
s=111 kph as the slower train
s+22=133 kph as the faster train
