Two stations A and B are 110 km apart o n a straight maid
line. One train starts from A at 7 a.m. and travels towards B at 20 kmph. Another train starts from B at
8 a.m. and travels towards A at aspeed of 25 kmph. At what time will they meet?

Answer 1

Answer:

10 a.m

Explanation:

suppose they meet X hours after 7 a.m

Distance covered by train by A in x hours is 20x km.

Distance covered by B in (x-1) hours = 25 (x-1) km.

therefore,20x+25(x-1)=110

45x= 135

x=3

so,they meet at 10a.m.

hope it helps!!
