Final answer:

Caitlin travels at a rate of 3.375 miles per hour, while Martin travels at a rate of 3.54 miles per hour. Therefore, Martin travels at a greater rate of miles per hour.

Step-by-step explanation:

To find the rate of miles per hour for Caitlin and Martin, we need to calculate their speeds.

Caitlin travels 4 1/2 miles in 1 13 hours. To calculate her speed in miles per hour, we divide the distance by the time: 4 1/2 / (4/3) = 4 1/2 * 3/4 = 27/8 = 3.375 miles per hour.

Martin travels 4 1/4 miles in 1 1/5 hours. To calculate his speed in miles per hour, we divide the distance by the time: 4 1/4 / (6/5) = 4 1/4 * 5/6 = 85/24 = 3.54 miles per hour.

Therefore, Martin travels at a greater rate of miles per hour.
