A Math Problem for the Idle

Lawnmowers need gas. With gas prices being rather ridiculous lately (and perhaps becoming more so in the future), what would be the most efficient way to mow a lawn? Assuming that your lawn is rectangular in shape and it takes you a fixed amount of time to mow a certain area, would it be better to mow in a clockwise/counterclockwise fashion or strictly rows back and forth? Let’s assume that turning the lawnmower to make another row in the latter scenario takes twice as long as the other.
