A mountain climber took 2 minutes to rappel down 60 feet. Which equation shows the correct calculation to show his movement per minute? –60(–2) = 30 –60 ÷ –2 = –30 –60 ÷ 2 = –30 60(–2) = 30

–60 ÷ 2 = –30

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Speed rate = distance / time

Replacing with the values given:

Speed rate = -60 ft /2 min

The distance is negative because the climber is going down.

So, the correct equation is:

–60 ÷ 2 = –30  

Feel free to ask for more if needed or if you did not understand something.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
