~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Divide 1/4 of a mile by 55 mph.

You will get the answer in hours.

        t = 1/4 : 55 = 1%2F%284%2A55%29 = 1%2F220 of an hour = 3600%2F220 seconds = 16 4%2F11 seconds = 16.363636... seconds.         ANSWER

The general rule for such problems is  THIS :   the travel time is the traveled distance divided by the average speed.

matrix%281%2C5%2C+++++DISTANCE%2C%22%22=%22%22%2CRATE%2C%22%22%2A%22%22%2CTIME%29

matrix%281%2C5%2C+++++1%2F4%2C%22%22=%22%22%2C55%2C%22%22%2A%22%22%2Ct%29

Multiply both sides by 4 to clear the fraction:

matrix%281%2C5%2C+++++1%2C%22%22=%22%22%2C220%2C%22%22%2A%22%22%2Ct%29

Divide both sides by 220

55%28miles%2Fhours%29%2At%28hours%29=%281%2F4%29miles

55t=1%2F4

t=1%2F%2855%2A4%29---------------- which is in hours. You might want to convert this to seconds or minutes.
