I feel like I'm losing my mind asking such an easy question, but for some reason I can't think of why the answer is double of what I'm calculating every time for this question.(adsbygoogle = window.adsbygoogle || []).push({});

After landing, a jet airplane comes to rest uniformly

(the acceleration is constant) in 11.5 seconds. The aircraft

rolls 1063.75 m. What was the landing speed? (in km/hr)

I keep getting 333 km/hr, but the answer is listed as 666 km/hr.

thanks
