Object will cover 21600 feet in 3 hours.
What is distance?
Distance is defined as the product of the speed and time.
The distance an object travelled is measured in distance per second here.
So, let us convert the hours into seconds to arrive at our answer.
One hour = 60 minutes = (60×60) seconds = 3600 seconds.
The object travels 2 feet for every second.
Then, total distance covered in 3 hours is
2×3×3600 = 21600 feet.
Hence, object will cover 21600 feet in 3 hours.
