To determine which statements are true about the distance Sal walks, we need to consider the proportional relationship between distance and time. If Sal walks \( D \) kilometers in \( T \) hours, we can express this as \( D = kT \), where \( k \) is a constant that represents the distance Sal walks per hour.
Let's analyze the statements one by one:
-
Sal walks 3.5 km in 1 h.
- This implies that \( k = 3.5 \). This statement is true.
-
Sal walks 1 km in 3.5 h.
- If \( k = 3.5 \) km in 1 h, then in 3.5 h, Sal would walk \( 3.5 \times 3.5 = 12.25 \) km, not 1 km. This statement is false.
-
Sal walks 4 km in 14 h.
- If we use \( k = 3.5 \), in 14 hours he would walk \( 3.5 \times 14 = 49 \) km. This statement is false.
-
Sal walks 14 km in 4 h.
- If \( k = 3.5 \), in 4 hours he would walk \( 3.5 \times 4 = 14 \) km. This statement is true.
Based on the analysis:
-
True statements:
- Sal walks 3.5 km in 1 h.
- Sal walks 14 km in 4 h.
-
False statements:
- Sal walks 1 km in 3.5 h.
- Sal walks 4 km in 14 h.
