Answer:
–60 ÷ 2 = –30
Explanation:
Calculation to determine the equation that shows the correct calculation to show his movement per minute
Using this formula
Speed rate = Distance / Time
Where,
Distance=-60 ft
Time =2 min
Let plug in the formula
Speed rate = -60 ft /2 min
Speed rate = -30
Based on the information given we were told that the climber rappel DOWN which is why the distance was negative.
Therefore the equation that shows the correct calculation to show his movement per minute is –60 ÷ 2 = –30
