Alright, lets get started.
In his first trip, Mr. Paul drove from drake to clay.
He drove 312 miles, took a break, and then drove 244 miles to clay.
It means the total distance between Drake to CLay will be [tex]312 + 244 = 556[/tex] miles.
On his trip back to drake from clay, he drove 305 miles before he took a break.
So, teh remainig part of his return trip will be = [tex]556 - 305 = 251[/tex] miles
He drive 251 miles the second part of his return trip : Answer
Hope it will help :)
