Answer:
Total distance Rory drive = 300 +142 = 442 miles
and total distance her cousin drive = 142 miles.
Explanation:
Total distance traveled by Rory and her cousins = 584 miles
Distance drive by Rory herself first day = 300 miles
Distance left to travel = total distance - distance drive by Rory
= ( 584-300 ) miles
= 284 miles.
According to the question, The second day, Rory and her cousin will share driving equally.
Let the distance traveled by cousin is S miles, then, Rory also drive S miles.
⇒ S + S = 284
⇒ 2S = 284
⇒ S = 142
So they will divide the remaining distance of 284 miles among them equally that is they both drive 142 miles.
Total distance Rory drive = 300 +142 = 442 miles
and total distance her cousin drive = 142 miles.
