This ratio also means that an unpowered hang-glider flying at a constant speed moves 15 metres forward for every one metre it descends.

这个比例也意味着一架无动力悬挂式滑翔机以恒定速率飞行时高度每下降1米，可以向前滑翔15米。

I would bet that a subtle error in the measured distance or time is more likely than that their ratio - the inferred speed - exceeds Einstein's speed limit.

我愿意打赌，更可能的情况是对距离或时间的测量中有一点细微的疏忽，而不是两者的比值(即推断所得的中微子速度)超过了爱因斯坦给出的速度上限。

Via the suite of onboard sensors the HUD, originally designed for snow sports, has been customized to display glide ratio, speed and altitude via a micro LCD screen sitting unobtrusively inside the pilot's goggle.

The inquiry heard that in second gear, in low ratio, the maximum speed was 18.2mph, but 39.7mph in high setting.

That may speed collection, but it also raises the risk-reward ratio of evasion.
