Question 368667
The formula to use is d=rt where d is the distance, r is the rate and t is the time. Identifying what has been given.
d = 35 miles    r = 50 mph  t = unknown
Plug into the formula
d = rt
35 = (50)x t
(35/50) = t
7/10 or .7 = t
But the question asks how long will it take to get there. We know there are 60 minutes in one hour so multiply (.7) by 60 minutes which gives 42 minutes.
