Praxis 5003 Practice Test Practice Question
Garden snails can move as slowly as 1/10 of an inch per second and as quickly as 1/2 inch per second. For a snail that is continuously moving, which of these times would be reasonable as to the amount of time it would take a snail to travel 20 inches?
Correct Answer: D
Rationale: To determine the time a garden snail would take to travel 20 inches, we can calculate the time using both the slowest and fastest speeds. At the slowest speed of 1/10 inch per second, it would take 200 seconds (20 inches ÷ 0.1 inches/second). At the fastest speed of 1/2 inch per second, it would take 40 seconds (20 inches ÷ 0.5 inches/second). Therefore, a time of 400 seconds is reasonable, as it fits within the range of possible speeds.
Option A (2 seconds) is far too quick, as even at maximum speed, the snail would take 40 seconds. Option B (10 seconds) is also unrealistic for the same reason. Option C (90 seconds) is not plausible since it exceeds the maximum speed calculation. Thus, 400 seconds is the only option that aligns with the possible travel times for a snail.
