Solution Steps

Step 1: Calculate miles per minute for Kevin's run

To find how many miles Kevin runs per minute, divide the total miles by the total minutes: \[ \text{Miles per minute} = \frac{4 \text{ miles}}{26 \text{ minutes}} \approx 0.15 \text{ miles per minute} \]

Step 2: Calculate cost per hour for bike rental

To find the cost per hour of bike rental, divide the total cost by the total hours: \[ \text{Cost per hour} = \frac{\$28}{8 \text{ hours}} = \$3.50 \text{ per hour} \]
