Question 2

The graphs below show the relationship between elapsed time and distance traveled by airplane A and airplane B after each airplane reaches its cruising speed.

Airplane C is traveling at a different cruising speed. The equation $y =\frac{27}{6}x$ can be used to determine $y,$ the number of miles traveled by airplane $	ext C$ in $x$ minutes. Which statement accurately compares the cruising speed of airplane $	ext C$ to airplanes $	ext A$ and $	ext B?$

Accepted Answer

The cruising speed of airplane $	ext C$ is less than the cruising speed of airplane $	ext A$ and greater
than the cruising speed of airplane $	ext B.$

Answer

The cruising speed of airplane $	ext C$ is less than the cruising speeds of both airplanes $	ext A$ and $	ext B.$

Answer

The cruising speed of airplane $	ext C$ is greater than the cruising speed of airplane $	ext A$ and
less than the cruising speed of airplane $	ext B.$

Answer

The cruising speed of airplane $	ext C$ is greater than the cruising speeds of both airplanes
$	ext A$ and $	ext B.$
