An Airplane travels about 1500km in a straight line between Toronto and Winnipeg . However, the plane must climb to 10 000 m dur
Lena [83]
Based on the given problem above, it requires a trigonometric solution. So here it goes:
The climb distance is:<span>200 * Sec <span>[<span>ArcTan <span>[10/200]</span></span>]</span> = 10</span>√ 401 km
and the decent distance is:<span>300 * Sec <span>[<span>ArcTan <span>[<span>10/300</span>]</span></span>]</span> = 10</span>√901 km
So add the given results above with 500 km and this will be the additional distance that <span>plane moves through the air.
The answer would be in the unit meters.
</span><span>(<span>(10</span></span>√401 +10√901−500)∗1000)=416 meters
Hope this is the answer that you are looking for.
