The distance traveled by a car varies directly with time
D = kt                     D = distance    k = speed of the car which is
                               t = time in hours                              constant
ex: what is the distance traveled by car at  70km/hr in 3 hrs
so      D = kt
               = 70*3 = 210km
you can see the distance traveled varies directly with time only
