The distance between station a and station B is 980km. The two trains leave each other. The fast train runs 50 kilometers per hour, and the slow train runs how many kilometers per hour to make the two trains meet in 10 hours

The distance between station a and station B is 980km. The two trains leave each other. The fast train runs 50 kilometers per hour, and the slow train runs how many kilometers per hour to make the two trains meet in 10 hours


980 △ 10-50 = 98-50 = 48 km / h



There are two trains running from a and B at the same time. The slow train runs 70 kilometers per hour, and the fast train runs 10 kilometers more than the slow train. Four hours later, the two trains run?


(70+70+10)×4
=150×4
= 600 km
