Final answer:
John was traveling at a speed of 57.91 miles per hour when he covered a distance of 1700 feet in 20 seconds.
Step-by-step explanation:
To calculate the speed at which John was traveling in miles per hour, we will convert the given distance to miles and the time to hours, then divide the distance by the time. There are 5280 feet in a mile and 3600 seconds in an hour.
First, convert 1700 feet to miles:
- 1700 feet × (1 mile / 5280 feet) = 0.322 miles
Next, convert 20 seconds to hours:
- 20 seconds × (1 hour / 3600 seconds) = 0.00556 hours
Finally, calculate the speed in miles per hour:
- Speed = distance / time
- Speed = 0.322 miles / 0.00556 hours = 57.91 miles per hour (rounded to two decimal places)
So, John was traveling at 57.91 miles per hour.
