Praxis 5003 Practice Question
A caterpillar travels 1 foot in 7.5 minutes. At this rate, how many feet does the caterpillar travel in 18 minutes?
Correct Answer: A
Rationale: To determine how far the caterpillar travels in 18 minutes, we first find its speed: 1 foot in 7.5 minutes translates to a rate of \( \frac{1 \text{ foot}}{7.5 \text{ minutes}} \). In 18 minutes, the caterpillar travels \( \frac{18 \text{ minutes}}{7.5 \text{ minutes/foot}} = 2.4 \text{ feet} \).
Option B (8 feet) overestimates the distance, assuming a faster rate. Option C (11.5 feet) is also incorrect, as it suggests an unrealistic speed. Option D (25.5 feet) assumes an even higher rate, which is not supported by the given information. Thus, 2.4 feet accurately reflects the caterpillar's travel in 18 minutes.
