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:

9.5 km/hr

Step-by-step explanation:

Let y be the speed of train from q

And let x be the speed of train from p

162/(x+y)=6--(1)

x-y=8---(2)

In (1)

x+y=162/6

     =27

From (1) and (2)

x+y=27

x-y=8

From solving

x=17.5 km/hr

y=9.5 km/hr
