Jean drove 64 miles per hour for a total of 448 miles on a trip. She used the equation below to calculate the time, t, it would take her to complete the trip.

Step-by-step explanation:

since there is no given formula I'm guessing that's what we want to find?

use the dist. = rate * time   formula for this kind of problem

or  d = r*t     ( this looks like the word  "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt  :P )  

so Jean's rate is 64 MPH

her total distance is 448 miles  

rearrange the  d = rt  formula so that you are solving for the thing you don't know.. yet   t (time)  for this case

s...

d/r = t

plug in number

448 / 64 = t

7 = t  (in hours)

true
