Answer:

d = 67t

and

eqn d = 67t represents d over time.

Step-by-step explanation:

part one : find the hours they have been driving

d = 603 miles driven

r = 67 mph

t = ?

r = d/t

rt = d

t = d/r

t = 603/67

t = 9

unit = in hours

they have been driving for 9 hours.

part 2 : find an equation for the situation that represents distance for any time

t is the independent variable

d will represent the dependent variable

let r represent the slope

d = rt

d = 67t

therefore the eqn d = 67t represents d over time.
