Question 1202685
??

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 <s>track</s> 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
------------------------------------------------------------


{{{RATE*TIME=DISTANCE}}}

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.

{{{5000*(1&1/2)=L+5}}}
(probably the wrong interpretation in "hour" for "1 ½ HOURS"; maybe should be "minutes").
