Question

A car is traveling at a speed of 55 miles per hour.you want to write an algebraic expression to show how far the car will travel in a certain number of hours. What will be your constant your variable

Answer 1

Speed=Distance/Time
So Distance=Speed X Time
Distance=55T
Where 55 is the Car's speed and it is constant(won't change) and T is the time which is the changing variable.
you can plug time values to know the distance traveled!
