Explanation:

Step1: Verify first statement

Check graph point (4,14): x=4 (hours), y=14 (km). This matches the statement "Sal walks 14 km in 4 h."

Step2: Verify second statement

Check graph point (1,3.5): x=1 (hour), y=3.5 (km). This matches the statement "Sal walks 3.5 km in 1 h."

Step3: Verify third statement

From proportionality, time for 1 km is $\frac{1}{3.5} \approx 0.286$ h, not 3.5 h. Statement is false.

Step4: Verify fourth statement

Time for 4 km is $\frac{4}{3.5} \approx 1.14$ h, not 14 h. Statement is false.

Answer:

Sal walks 14 km in 4 h.
Sal walks 3.5 km in 1 h.
