29.33 ft/sec is speed in feet per second.
20 miles= 105600 ft
1 hour= 3600 second
speed= distance/time
speed=105600/3600
speed=29.33 ft/sec
It is possible to express how much an object's location shifts over time or how much it shifts per unit of time using a scalar variable called speed. It is frequently abbreviated to "s." The distance traveled by an object divided by the duration of the period gives the average speed of the object over the period.
The speed-related metric is time divided by distance. While the meter per second (m/s) is the SI unit of speed, the kilometer per hour (kph) is the most widely used unit in daily life (kph).
