Let x=time to finish 2nd half of the exam.
2x/3 + x = 60
2x+3x=180 multiply each side by 3 to eliminate fraction.
5x=180
x=36
2*36/3=24 min to finish 1st half of the exam.

A student finishes the first half of an exam in 2/3 the time it takes him to finish the second half. If the entire exam takes him an hour, how many minutes does he spend on the first of the exam?
------------------------------------------------
Let the time for the 2nd half be "x".
Then the 1st half takes (2/3)x
----------------------------------
Equation:
x + (2/3)x = 60 minutes
(5/3)x = 60
5x = 180
x = 36 minutes
(2/3)x = (2/3)36 = 24 minutes (time spent on the 1st half of the exam)
