Mr. Mole left his burrow and started digging his way down.

A represents Mr. Mole's altitude relative to the ground (in meters) after t minutes.

A = - 2.3t - 7

How fast did Mr. Mole descend?

He's descending at a pace of 2.3 meters per minute.

Step-by-step explanation:

This is because the equation shows us the slope or the speed he's going at.

A = - 2.3t - 7

A = Altitude

-2.3 = Slope

- 7 is his starting altitude in meters

But every minute, t, he is going down 2.3 meters. It's easier to think about if you consider, A = y, and, t = x. Now you have the equation, y = - 2.3x - 7.

And you graph it to see the progression in slope.
