Question

Karthik and Srinu are climbing on a moving escalator that is going up. Karthik takes 25 steps to reach the top but Srinu takes 40 steps to reach the top. Karthik can take 5 steps in a second while Srinu can take 10 steps in a second. Calculate the total number of steps in the escalator.​

Answer 1

Answer:

Let distance to be traversed = x.

Speed of escalator =t1x

Speed of man walking =t2x

When the man is walking on a moving escalator, speed is =x(t21+t11)=xt1t2(t1+t2)

Time taken is distance by speed =vx=t1+t2t1t2
