Mileage?

I don't get cars and I don't understand the fascination over them. Ryan got a new civic and the guys were talking about how far the car travels on a full tank.

"500+"

I was like, 'wah 500+ mins?"

I mean.. sounds logical right for a car to be on the road for 500 mins? It is possible right? But the guys kept giving me stares like I was some moron.

Apparently they were talking about 500+km.. LIKE HOW THE HELL WOULD I KNOW!
