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 75 km more than the other. What is the distance between the two stations?
Choices.
A) 540 km	B) 675 km	C) 276 km	D) 178 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 75km more than the other,   25x â€“ 20x = 75   5x = 75   x = 15 hours   As the two trains are moving towards each other, relative speed = 20 + 25=

45 km/hr   Therefore, total distance= 45*15=
