Please help me. I am terrible at math. Even the simplest problem I can make very complicated.

Speed is a ratio of distance to time, and this is expressed as a fraction. The UNITS should be connected to each number. This helps in calculations.

45 miles per hour means %2845%2F1%29%28MILES%2FHOUR%29.

SPEED=DISTANCE%2FTIME
If multiply left and right sides by TIME, the result is still a correct equation.
SPEED%2ATIME=TIME%28DISTANCE%2FTIME%29

highlight_green%28SPEED%2ATIME=DISTANCE%29


How far traveled in 3.6 hours, if the travel were done at %2845%2Amiles%29%2F%281%2Ahour%29?

%28%2845miles%29%2F%281%2Ahour%29%29%2A3.6%2Ahours

%2845%2A3.6%2Amiles%29%2F1

162 miles
