Speed Time & Distance Quants MCQs with Answer - Exercise II


Ques 1 Speed and Time

A train 180 m long moving at the speed of 20 m/sec overtakes a man moving at a speed of 10 m/sec in the same direction. The train passes the man in
  a) 9 sec
  b) 18 sec
  c) 27 sec
  d) 36 sec


b is the correct option
Let's call the time it takes for the train to overtake the man "t".
During this time, the man covers a distance of 10 * t meters, and the train covers a distance of 20 * t + 180 meters.
The train must cover a distance equal to the length of the train plus the distance covered by the man, so we have:
20 * t + 180 = 10 * t + 180
Solving for t, we get:
10 * t = 180
t = 18 seconds
So, the train passes the man in 18 seconds, and the correct answer is b) 18 sec.
