Question

logical question:
total time to cover DISTANCE AB=>t=12 hours
A---------------B

ever hour a bus starts coming from A and B ,how many buses coming from point B will be seen my a bus coming from A

Answer 1

It takes 12 hours to get from point A to point B, thus in that time 12 buses will have started the journey from B to A.

Answer 2

It has to meet every bus that has started a journey at some point.

Answer 3

oh

Answer 4

use Graphical Methods

Answer 5

Well, it's 12 if you assume there are no buses on the road when A departs

Answer 6

what's the answer for that ?

Answer 7

If you assume there were buses on the road... well the road can fit 12 at most, so it would meet 24 all together.

Answer 8

Answer 13

btw can we solve it by using any formula?

Answer 14

No, the problem is too simple to require a formula.

Answer 15

oh actually it's a physics question so i was wordering whther it could be solved by applying formulae or not coz there are similar questions based on it which are solved by using formulae

Answer 16

Well, there are two states.

Answer 17

The first half of the journey will have no approaching vehicles. After that it is like a wave.
