Better and faster way of doing problem 185 will be (in my opinion)

X took 2 hrs to do 80 miles thus 40 miles per hour.

Y traveled 50% faster thus 40 miles per hour times 1.5= 60 miles per hour

Car covers first sixty miles in 1 hr and only 20 miles are left which is 1/3 of an hour. So your answer is 1 1/3 C
