Multiple choice

Two trains 130 m and 110m long are going in the same direction. The faster train takes one minute to pass the other completely. If they are moving in opposite directions, they pass each other completely in 3 seconds. Find the speed of each train?

  1. 42 m/s, 38 m/s

  2. 36 m/s, 42 m/s

  3. 38 m/s, 36 m/s

  4. 40 m/s, 36 m/s

  5. 42 m/s, 36 m/s

A Correct answer
Explanation

Let speeds be v1, v2. Same direction: (v1 - v2) = (130 + 110) / 60 = 4 m/s. Opposite direction: (v1 + v2) = (130 + 110) / 3 = 80 m/s. Solving: 2v1 = 84, v1 = 42; 2v2 = 76, v2 = 38. Option A is 42, 38.
