To convert Caroline's walking speed from inches per second to miles per hour, we need to perform a series of conversions.
Step 1: Convert inches to feet by dividing 9 1/2 inches by 12 (since there are 12 inches in a foot).
9 1/2 inches = (9 + 1/2) / 12 feet = 9.5 / 12 feet
Step 2: Convert feet to miles by dividing the result from Step 1 by 5,280 (since there are 5,280 feet in a mile).
9.5 / 12 feet = 0.7916667 feet
0.7916667 feet = 0.7916667 / 5280 miles
Step 3: Convert seconds to hours by dividing 1 by 3,600 (since there are 3,600 seconds in an hour).
1 second = 1 / 3600 hours
Step 4: Multiply the conversions from Steps 2 and 3 to get the walking speed in miles per hour.
(0.7916667 / 5280) miles × (1 / 3600) hours = 0.0001984 miles per hour
Therefore, Caroline walks approximately 0.0001984 miles per hour.
