Here's how to convert miles per hour (mph) to feet per second (fps):

1. Conversion Factors:

* 1 mile = 5280 feet

* 1 hour = 3600 seconds

2. Calculation:

* Step 1: Convert miles to feet: 38 mph * 5280 feet/mile = 200,640 feet/hour

* Step 2: Convert hours to seconds: 200,640 feet/hour / 3600 seconds/hour = 55.73 feet/second

Therefore, you travel at approximately 55.73 feet per second when traveling at 38 mph.
