Step 1
Given data:
The thickness of ice is
The rate of deposition is
Step 2
Part (a)
The standard linear function is given by,
The function of thickness can be given by,
Here, x is the time in hour.
Thus, the linear function is
Step 3
Part (b)
Given that the time is
Substitute value of x in linear function as calculated in part (a),
Thus, the thickness of ice layer is 0.545 in after 1.5 hr.
