If a plane accelerates from 0 to 180 knots in 9 seconds, how much total speed does it gain?

• A. 160 knots
• B. 180 knots
• C. 200 knots
• D. 220 knots

Answer: (B)

In this scenario, the plane starts with an initial speed of 0 knots and accelerates to a final speed of 180 knots. To determine the total speed gained, one simply calculates the difference between the final speed and the initial speed. Since the initial speed is 0 knots, the total speed gained is equal to the final speed of 180 knots. This means the plane has gained 180 knots over the 9 seconds of acceleration. Understanding speed gain in such a context focuses on the change from the initial state to the final state, which in this case is a straightforward calculation resulting in a gain of 180 knots.
