Jaime finishes 15 math problems in 2.5 hours.. How many math problems can he finish in 8 hours? 

To determine how many math problems Jaime can finish in 8 hours, we'll first calculate his rate of solving problems per hour, and then use this rate to find out how many problems he can solve in 8 hours.

### Step 1: Calculate Jaime's rate of solving problems

Jaime's rate is:

\[
\text{Rate} = \frac{15 \text{ problems}}{2.5 \text{ hours}} = \frac{15}{2.5} = 6 \text{ problems per hour}
\]

### Step 2: Calculate the number of problems he can finish in 8 hours

Using the rate found in Step 1:

\[
\text{Problems in 8 hours} = 6 \text{ problems/hour} \times 8 \text{ hours} = 48 \text{ problems}
\]

### Answer:
Jaime can finish **48 math problems** in 8 hours.
