Question 745720: The problem says: "A car is traveling at the speed of 55 mph.You want to write an algebraic expression to show how far the car will travel in a certain number of hours. What will the constant? The Variable?" i know the constant is a number that stays the same and doesnt change, so im assuming that it would be the speed, right?
I think that the variable would be the number of hours. But im not sure if i need to multiply or divide. Would it be 55x? x= the time traveled... Am I correct?

:
I think you're right
:
The equation will be
d(x) = 55x
where
d(x) = the distance as a function of time
x = the variable, time in hours
55 = the slope
there is no constant
