Well, you can use the distance formula for this:
d = rt where d = distance traveled, r = rate (speed) of travel, and t = the time used in traveling, so...
d = 55t where t (time) is the variable and there is no constant or, to put it another way, the constant is zero.

d=rt Start with the distance-rate-time formula


d=55t Plug in r=55


So in "t" hours, the car will travel 55t miles. For instance, if t=2, then 55t=55%282%29=110 which means in 2 hours the car travels 110 miles.


So the algebraic expression for the distance is 55t where 55 is the coefficient (in this case there is no constant) and t is the variable
