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

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
