Answer 2

.

The easiest way to convert units, for me, is to set it up as a multiplication problem.

(90 km) x (1000 m / 1 km) x (1 hr / 60 min) x (1 min / 60 sec)= 25 meters / second

If you start with what you know and multiply by the conversions you know the conversions all cancel out to what you are looking for and the answer pops out in the correct units.
