Answer:

6/5

Step-by-step explanation:

The average time you spent per problem for the first 20 problems is 25/20 = 5/4 minutes. There are 40 - 25 = 15 minutes remaining, and 30 - 20 = 10 problems remaining, so the average time per remaining problem is 15/10 = 3/2 minutes. Hence, you can spend

(3/2)/(5/4) = 6/5

times longer on the remaining problems.

The number of remaining problems is:
 30-20 = 10 problems.
 The amount of time remaining is:
 40-25 = 15minutes
 For the first 20 problems the time per problem is:
 t1 = 25/20 = 5/4 minutes
 For the remaining problems the time per problem is:
 t2 = 15/10 = 3/2 minutes
  Answer:
 
you will be able to spend about 3/2 minutes on each remaining problem
