.

The formula  d = rt  gives   140 = 35*t,


so, to find the time "t", you should divide 140 by 35

    t = 140%2F35 = 4 hours.

Solved, with all necessary auxiliary explanations.

d=140%2Amiles
-
r=35%28miles%2Fhour%29
-
t=d%2Fr

Or this can be arranged using the units of the numbers.
140%2Amiles%2A%281%2F35%29%2A%28hour%2Fmiles%29
and simplify and compute this time.
