**Question:**

A father walks 36 miles in 12 hours. While his son covers the same distance on a bicycle at twice the father’s rate of speed. At this rate, how many miles would the bicycle rider travel in 9 hours?

**Solution Steps:**

1. **Determine the father’s walking speed:**
   - Distance = 36 miles
   - Time = 12 hours
   - Speed = Distance/Time = 36 miles / 12 hours = 3 miles per hour

2. **Calculate the son’s bicycle speed:**
   - Son’s speed = 2 * Father’s speed
   - Son’s speed = 2 * 3 miles per hour = 6 miles per hour

3. **Calculate the distance the son would travel in 9 hours:**
   - Distance = Speed * Time
   - Distance = 6 miles per hour * 9 hours = 54 miles

**Answer:**

The bicycle rider would travel 54 miles in 9 hours.
