Which term describes the horizontal distance in feet per minute?

• A. Vertical Speed
• B. Horizontal Speed
• C. Traveling Cable
• D. Call/Send Controls

Answer: (B)

The idea being tested is that a rate described by feet per minute can refer to movement along a horizontal direction as horizontal speed. Horizontal speed is the rate at which you cover horizontal distance, measured in feet per minute, regardless of how much you rise vertically. In escalators and moving walks, movement has a vertical component (the rise per minute) and a horizontal component (the distance traveled along the floor per minute). The term that fits “horizontal distance in feet per minute” is horizontal speed. The other options describe different things: vertical speed is the rate of vertical rise, a traveling cable is a power/signal cable, and call/send controls are the remote start/stop control system.
