Two cars A and B are separated by a distance
of 0.5 km and moving in the same direction
with same speed. A car C moving with 10 km/h
in opposite direction meets these cars at an
interval of 1 minute. The speed of A and B is
दो कार A तथा B 0.5 km दूरी से पृथक्कृत हैं तथा सम्मान
चाल से समान दिशा में गतिशील हैं। विपरीत दिशा में 10
m/h से गतिशील एक कार C,1 मिनट के अन्तराल पर इन
कारों से मिलती है। A तथा B की चाल है
(A) 20km/h​

Answer 1

Answer:

This is related to relative motion,

Let the two cars moving in the same direction be A and B and the third car be C.

Let the velocity of C be 'u'.

So the velocity of C with respect to B would be. u+30(as they are moving in opposite directions).

Do the speed u+30 would be given by:

=(604​)5​=u+30

⇒5×460​=u+30⇒75=u+30

Hence u=45kmph
