part 1 of 3
a student runs 4 minutes for every 20 minutes he walks.
a. complete the table. graph the pairs of values.
b. for how long would the student walk if he runs for 10 minutes?

a. complete the table.
running (min) walking (min)
4 20
8
12
(type whole numbers.)

Explanation:

Step1: Find walking ratio per run min

First, calculate the walking time per 1 minute of running:
$\frac{20}{4} = 5$ minutes of walking per 1 minute of running.

Step2: Calculate walking for 8 min run

Multiply running time by the ratio:
$8 \times 5 = 40$

Step3: Calculate walking for 12 min run

Multiply running time by the ratio:
$12 \times 5 = 60$

Step4: Solve part b: 10 min run

Multiply 10 by the ratio:
$10 \times 5 = 50$

Answer:

a. Completed table:

Running (min)	Walking (min)
8	40
12	60

b. 50 minutes
