1 hour is equivalent to 3600 seconds.

20 meters per second for 3600 seconds is equal 72000 meters per hour.

72000 meters per hour divided by 100 is equal to 72 kilometers per hour.

you will not get a speeding ticket.

Make unit multipliers:



Cancel the meters



Cancel the seconds



Cancel the minutes



And all we have left is

or
