Answer:
Answer
Total distance between A and B=330km/ht.
∵ A start from A at 8.00a.m and B at 9.00a.m
Time span=1hour.
∴ Distance traveled by A in 1hr=60km.
Now distance left when B will start=(330−60)km =270km
Relating speed of train A and B =60km/hr+75km/hr
=135km/hr
(Speed added because both train traveled towards each others.)
∴ Time taken to meet A and B=
135km/hr
270km
