Question

Train A starts moving at 8 am from Delhi station with velocity of
100 km/h and train B starts from Jaipur station at 9 am with
velocity of 50 km/h. If the distance between Jaipur to Delhi is
700 km. then at what time will they meet with each other?​

Answer 1

Answer:

1 pm

Explanation:

train A starts from 8am from delhi with velocity of 100km/hr

train B starts at 9am from Jaipur with velocity of 50km/hr

therefore till 9am train A cover 100km

therefore the distance left is 600km

the relative velocity of train A and B=150km/hr

distance left=600km

time =distance/speed

time =600/150

time =4 hr

therefore we consider the time from 9am so after 4hr both train will meet

therefore the time after train meet is 1 pm
