A slug travels 3 inches in 3 minutes. A snail travels 6 centimeters in 6 seconds.

• No, because speed depends on both distance and time, not just distance.

• Yes, because the snail traveled a greater distance.

• Yes, because the snail traveled for a shorter time.

• No, because the slug traveled for a longer time.
