Question 156854
{{{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(2)=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
