ROAD
SIGN
DRIVING TIP:
For example, when you see a sign that is shown as
90 km/h (90 kilometers per hour)
and you
want a quick conversion to mph (miles per hour) simply multiply 6 x 90
in your head
and you are going
approximately 54 miles per hour.
1 kilometer
per hour (km/h) is equal to
.6214 miles per hour

A car traveling at 90 km/h
is moving at 90 kilometers per hour
THAT'S EASY!
