Question

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

Answer 1

–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
