Paola uses a fitness application on her phone to track how many miles she walks per day. Before a hike, she notes that her mile count is at 1.5. In general, Paola knows that her walking speed is around 3 mph. From this information, she develops the equation y = 3x + 1.5 to represent the total number of miles, , her phone will show after X hours on the hike.

PART A

Complete the table with the total number of miles shown on Paola's phone after X hours.

Hours (X) Total Miles (Y)
0 ---- 1.5
1 ---- (blank)
2 ---- (blank)
3 ---- (blank)

1 answer

To find the total number of miles (Y) shown on Paola's phone after \( X \) hours, we can use the equation \( y = 3x + 1.5 \).

Let's calculate \( Y \) for each hour value in the table:

  1. For \( X = 0 \): \[ Y = 3(0) + 1.5 = 1.5 \]

  2. For \( X = 1 \): \[ Y = 3(1) + 1.5 = 3 + 1.5 = 4.5 \]

  3. For \( X = 2 \): \[ Y = 3(2) + 1.5 = 6 + 1.5 = 7.5 \]

  4. For \( X = 3 \): \[ Y = 3(3) + 1.5 = 9 + 1.5 = 10.5 \]

Now, let's fill in the table:

| Hours (X) | Total Miles (Y) | |-----------|------------------| | 0 | 1.5 | | 1 | 4.5 | | 2 | 7.5 | | 3 | 10.5 |
