Two trains start at same time from two stations and proceed towards each other at the rate of 20 km/hr and 25 km/hr respectively. When they meet, it is found that one train has traveled 50 km more than the other. What is the distance between the two stations? Pick:
A) 540 km	B) 767 km	C) 276 km	D) 450 km	E) 176 km
Explanation:   Let us assume that trains meet after 'x' hours   Distance = speed * Time   Distance traveled by two trains = 20x km and 25x km resp.   As one train travels 50 km more than the other,   25x â€“ 20x =50   5x = 50   x = 10 hours   As the two trains are moving towards each other, relative speed = 20 + 25=

45 km/hr   Therefore, total distance= 45*10=
