Jaime finishes 15 math problems in 2.5 hours. 

a. How many math problems can he finish in 8 hours? 

To find out how many math problems Jaime can finish in 8 hours, we first need to determine his rate of completing math problems per hour. Then we can use that rate to calculate the total number of problems he can finish in 8 hours.

### Step-by-Step Solution:

#### 1. Calculate Jaime's rate of completing math problems:

Jaime finishes 15 math problems in 2.5 hours. 

\[
\text{Rate of problems per hour} = \frac{\text{Number of problems}}{\text{Time in hours}}
\]

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

To simplify the division:

\[
\text{Rate of problems per hour} = \frac{15}{2.5} = \frac{15 \times 10}{2.5 \times 10} = \frac{150}{25} = 6 \, \text{problems per hour}
\]

#### 2. Use the rate to find out how many problems Jaime can finish in 8 hours:

Now that we know Jaime completes 6 math problems per hour, we multiply this rate by the total number of hours (8 hours):

\[
\text{Number of problems in 8 hours} = 6 \, \text{problems per hour} \times 8 \, \text{hours}
\]

\[
\text{Number of problems in 8 hours} = 48 \, \text{problems}
\]

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