**Problem 1:** After Julia has driven for half an hour, she was 155 miles from Denver. After driving for 2 hours, she was 45 miles from Denver. Assume that Julia drove at a constant speed. Let f be a function that gives Julia’s distance from Denver after having driven for *t* hours.

- Determine a rule for the function
*f*.

Step 1

Given,

After driving half an hour, Julia is 155 miles from Denver.

And

After driving 2 hours, Julia is 45 miles from Denver.

Let the points be

Step 2

Since, it is given that Julia is moving with constant speed.

Therefore,

Step 3

Therefore...
