Question

select the correct answer in each row.
scenario | speed | velocity
a student walks to school a total distance of 2 kilometers in 18 minutes. | ○ | ○
a bee flies from one flower to another in a straight line, traveling 1 meter east in 2 seconds. | ○ | ○
a family drives to the store and then to a friend’s house for a total displacement of 10 km south and a total time of 12 minutes. | ○ | ○
a car travels 24 meters per second. | ○ | ○

Explanation:

To determine whether each scenario involves speed or velocity, we use the definitions:

• Speed is a scalar (magnitude only, no direction).
• Velocity is a vector (magnitude + direction).

Row 1: Student walks 2 km in 18 min

• Distance (2 km) and time (18 min) → speed (scalar, no direction).
• Select: Speed

Row 2: Bee flies 1 m east in 2 s

• Magnitude (1 m) + direction (east) → velocity (vector).
• Select: Velocity

Row 3: Family drives 10 km south in 12 min

• Displacement (10 km south) + time → velocity (vector, includes direction).
• Select: Velocity

Row 4: Car travels 24 m/s

• Only magnitude (24 m/s), no direction → speed (scalar).
• Select: Speed

Answer:

• A student walks to school a total distance of 2 kilometers in 18 minutes: Speed
• A bee flies from one flower to another in a straight line, traveling 1 meter east in 2 seconds: Velocity
• A family drives to the store and then to a friend’s house for a total displacement of 10 km south and a total time of 12 minutes: Velocity
• A car travels 24 meters per second: Speed
