The truck's speed is:
km/hr
-------------------
The car's speed is:

km/hr
------------------------
In terms of just units:
[ km/hr ]x( hrs/min ]x[ min/sec ] = km/sec
then,
[ km/sec ]x[ sec ] = km
-------------------------
= .015 km/sec
and
km
-----------------------
convert to meters
[ km ] x [ m/km ] = m

The car goes 225 m in 15 sec
