Ram and Krishna start from A and B respectively at the same time and travel towards each other at constant speeds along the same route. Ram meets Krishna at point C on the road which is 900m away from starting point A and 600m away from point B. The time taken by Ram to reach point B is 20minutes. Find the constant speed of Krishna. Pick:
A) 50 m/m
B) 60 m/m
C) 40 m/m
D) 53.5 m/m
E) none of the above
total distance from A to B-   A - C = 900m, B - C = 600m;   therefore A-B = 1500m;   Vr=1500/20=
