part a
how many miles per hour did jack drive?
part b
jack will drive 520 more miles at the same rate. how long will it take jack to drive the 520 miles?

Explanation:

Step1: Calculate Jack's speed

Use $\text{Speed} = \frac{\text{Distance}}{\text{Time}}$
$\text{Speed} = \frac{325}{5} = 65$ miles per hour

Step2: Calculate time for 520 miles

Use $\text{Time} = \frac{\text{Distance}}{\text{Speed}}$
$\text{Time} = \frac{520}{65} = 8$ hours

Answer:

PART A: 65 miles per hour
PART B: 8 hours
