Answer:

Step-by-step explanation:
Mr.Mole's digging can be described by a linear model of general equation:

Where "m" is the rate at which he descends. Note that since the function A(t) measure his altitude relative to the ground, the rate "m" must be negative.


The constant "c" is his starting position. To find this value, assign the given data at t = 5 min to the equation above

Therefore, the function A(t) is described by the following formula:

0.08 is the answer to your question. If you have a calculator use it.
Answer:
Ok well it’s obviously not 140 Bc that’s more Doctors than they had to start and it isn’t 20, it’s not 40, so it’s 60.
Step-by-step explanation:
Also if you do 100/5 you get 20 and 5-2 is 3 so 20 times 3 is 60 so yeah
