Answer:
 120 days
Explanation:
Using the formula for simple interest, we can solve for t:
 I = Prt
 t = I/(Pr) = 608/(22800×.08) = 608/1824 = 1/3 . . . . year
For "ordinary interest", a year is considered to be 360 days, so 1/3 year is ...
 (1/3)(360 days) = 120 days
It will take 120 days for the loan to earn 608 in interest.
