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. After meeting at a point between A and B, Sam and Nik proceed to their destinations of B and A respectively. Sam reaches B 60 minutes after the two meet and Nik reaches A 90 minutes after their meeting. How long did Sam take to cover the distance between A and B?
Choices:
A) 60 minutes
B) 120 minutes
C) 200 minutes
D) 225 minutes
E) none of the above
t-time taken for A120 minutes to meet   (Vs+Vn)t=Vs*60+Vn*90;   Vs(t-60)=Vn(90-t)   This means 60&lt;t&lt;90   so ans will be 60+t   Only 120 minutes fits this eqn
