Question

A train of length 150metre running at a speed of 40km took one minute to overtake another train running in a speed of 22km in the same direction.what is the length of second train,

Answer 1

Answer:

150 metre

Step-by-step explanation:

let the length of second train= Y metre

since, speed= distance / time

=> respective speed=

total length / time taken to overtake

=> (40-22) ×1000/(60×60)=( 150+Y) / 60

=> 18×50/3= 150+Y

=> Y= 300-150= 150 metre
