<PRE><B>Question 88712</B>
Ariana took 2 hrs longer to drive 360 miles on the first day of a vaction trip than to drive 144 miles the second day. If his average driving rate was the same both days what was the driving time each day?
------------
1st day DATA:
time = x+2 hrs; distance = 360 miles; rate = d/t = 360/(x+2) mph
-------------
2nd day DATA::
time = x hrs; distance = 144 miles; rate = d/t = 144/x mph
---------------
EQUATION:
rate = rate
360/(x+2) = 144/x
360x = 144x + 288
216x = 288
x = 1 1/3 hrs (time on 2nd day)
x+2 = 3 1/3 hrs (time on 1st day)
