Sam and Nik start from A and B respectively at the same time and travel towards each other at constant speeds along the same route. Sam meets Nik at point C on the road which is 600m away from starting point A and 400m away from point B. The speed of Sam is 50 m/m(meter/minute). How much time did Sam take to cover the distance between A and B? Select
A) 10 minutes  B) 15 minutes  C) 20 minutes  D) 22 minutes  E) 17 minutes
total distance from A to B-   A - C = 600m, B - C = 400m;   therefore A-B = 1000m;   Vs=50 m/m;   therefore,   t = 1000/50=
