Kenny engages in up to 3 types of exercise each week for a total of 6 hours while training for a triathlon. Kenny swims for the same number of minutes each week. The equation $y=360-x-170$ represents the situation where Kenny bikes for $x$ minutes during a week and runs for any remaining training time $y$, in minutes. If this equation is graphed in the $xy$-plane, which statement is the best interpretation of the $x$-intercept of the graph?

A

During a week when Kenny doesn’t run, he bikes for 190 minutes.

B

During a week when Kenny doesn’t bike, he runs for 190 minutes.

C
