Question

on a particular day from jaipur to delhi, buses ran at intervals of 40 min while from delhi to jaipur they ran at intervals of 45 min. at what earliest time would two bused coming from opposite directions pass a particular bridge if they passed the same bridge at 10.15 a.m.?

Answer 1

Answer:

It is given that Buses ran from

Jaipur to Delhi at an interval of

40 minutes

and Buses ran from Delhi to

Jaipur at an interval of 45

minutes.

That is after every 40 minutes, a

bus departs from Jaipur to Delhi

and after every 45 minutes, a bus

departs from Delhi to Jaipur.

Since the two buses passed the

same bridge at 10 15 am.

The next bus from Jaipur will

come after 40 minutes, that is at

10: 55 am

Also, the next bus will come from

Delhi after 45 minutes, that is at

11 00 am

Thus the required earliest time is

10: 55 am
