To define the number of miles a jet travels in direct variation, you can use the equation:
\[ y = kx \]
where \( y \) is the distance traveled, \( k \) is the rate (in miles per hour), and \( x \) is the time (in hours).
Given that the jet is flying at a rate of 600 miles per hour for 3 hours, the correct equation reflecting this situation would be:
\[ y = 600x \]
For the specific scenario of traveling for 3 hours, you substitute \( x = 3 \):
\[ y = 600 \times 3 \]
So, the answer from the options you provided would be:
d. y = 600 * 3
This equation indicates that after 3 hours, the jet travels \( 600 \times 3 = 1800 \) miles.
