Question

Two places P & Q are 162 km apart. A train leaves P for Q & simultaneously another train leaves Q for P. They meet at the end of 6 hours. If the former train travels 8 km/hr faster than the other train, then the speed of train from Q is

Answer 1

Answer:

9(1/2)km/hr

Step-by-step explanation:

Let the speed of the train from Q be X km/hr

Then the speed of the train from P is ( X+8 ) km/hr

They meet each other at M after 6 hours travel

PM + MQ = 162 km

6 ( X + 8 ) + 6X = 162 km

12X + 48 = 162

12X = 162 - 48

12X = 114

X = 114/12

9 (1/2) km/hr
