A mountain climber took 2 minutes to rappel down 60 feet. Which equation shows the correct calculation to show his movement per minute?

The climber moved downward 60 feet, so the change in position is −60 feet. It took 2 minutes, so divide the change in position by the time: −60 ÷ 2 = −30 feet per minute. This matches choice C, “−60 ÷ 2 = −30.”
