Question

At time t​=0, water begins to drip out of a pipe into an empty bucket. After 48 ​minutes, there are 12 inches of water in the bucket. Write a linear function rule to model how many inches of water w are in the bucket after any number of minutes t.

Answer 1

W = (1/7) t

Explanation:

At t = 0, W = 0

At t = 56 minutes , W = 8 inches

W = k*t The y intercept = 0 because t = 0 W = 0

8 inches = k * 56 minutes

k = 8 / 56

k = 1/7 inches / minute

W = (1/7) t
