53.Two stations A and B are 110 km apart on a straight 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 a speed of 25 kmph. At what time will they meet ?
A. 9 a.m B. 10 a.m
C. 10-30 a.m D. 11 a.m
Answer:
Distance covered by A in x hours = 20 x km
Distance covered by B in (x - 1) hours = 25 (x - 1) km
= 20x + 25 (x - I)
= 110
= 45x = 135
x = 3. So, they meet at 10 a.m
