This is very easy to understand if you just restate it
as:
" Mark off a distance along the tracks which is equal
to the length of the train. At 45 mi/hr, the engine
covers this distance in 12 sec. What is the length
that was marked off?"
Note that sec x min/sec x hr/min
= hrs
km
km x m/km =
The train is 150 m long
