Question 1202685:
A passenger train travelling at 25km/hr is moving in the same direction as the truck travelling at 30km/hr. the railway line runs parallel to the road and the track takes 1 ½ minutes to overtake the train completely
(a) Given that the truck is 5 metres long determine the length of the train in metres
(b) The track and the train continue moving parallel to each other at the original speeds. Calculate the distance between them after 4 minutes and 4 seconds after the track overtake the train
(c) The track stopped 45 minutes after overtaking the train. How long did the train take to catch up with the truck Found 2 solutions by mananth, josgarithmetic:Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! (a) Given that the truck is 5 metres long determine the length of the train in metres
convert km/h to m/s
Truck speed - train speed
Catch up speed = 1.389 m/s
Distance to cover is length of train and Truck
Let length of train be x meters
time = 1 1/2 min = 90 seconds
(5+x) = 1.389*90
5+x = 125.01
x = 120 m approx

Maybe you mean like so:
----------------------------------------------------------
A passenger train travelling at 25km/hr is moving in the same direction as the truck travelling at 30km/hr. the railway line runs parallel to the road and the track TRUCK takes 1 ½ HOURS to overtake the train completely
(a) Given that the truck is 5 metres long determine the length of the train in metres
------------------------------------------------------------
L, unknown length of the train
speed of truck along the train, 30-25=5 kilometers per hour;
which is 5000 meters per hour.
The front end of the truck must travel to cover L+5 meters.
(probably the wrong interpretation in "hour" for "1 ½ HOURS"; maybe should be "minutes").
