Question 588270: Train P has a length of 250 meters and is traveling at the speed of 45 km/hr. Train Q has a length of 110 meters, and is traveling on parallel tracks in the same direction , and Train Q is overtaking Train P, how long will the faster train take to completely overtake the slower one ( from the moment they meet) ?
Thanks.

Train P has a length of 250 meters and is traveling at the speed of 45 km/hr.
Train Q has a length of 110 meters, and is traveling on parallel tracks in the same direction, and Train Q is overtaking Train P,
how long will the faster train take to completely overtake the slower one ( from the moment they meet) ?
:
They don't give us speed of to train Q
Let Q = speed of train Q
:
Time = dist/speed
:
Time to overtake = %28%28250%2B110%29%29%2F%28%28Q-45%29%29}
