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
Answer:
-2
Step-by-step explanation:
7−5+3−1
using BODMAS
A is addition and it comes before subtraction
7−(5+3)−1
7-8-1

Best of luck in your studies :)
