两道英文数学题求翻译成中文
第一道:
A perpendicular bamboo stalk 18 meters high was broken by the wind.
The stalk was bent over so that its tip touched the ground 6 meters from its base.
How high up the stalk was the break?
第二道:
Tow planes leave the same place and fly, in a straight line, in opposite directions.
The average speed of one plane is 18 km/h faster than the other.
Find the speed of each plane if they are 1179 km apart after 1.5 hours.
不要网络直译,我用翻译器翻的都看不懂

第一题:18米高的竹竿被风折断(但是还连着,没有完全断开),折断后的竹竿尖(竹梢)碰到地面的地方离原竹竿根部6米,问折断的地方是原来竹竿多高的地方.(我猜想这是个直角三角形,勾股定理的题目.底边为6,三角形另外两边之和是18,设最终答案,也就是垂边为x,那么 x^2+6^2=(18-x)^2,算出来答案应该是8米)
第二题:两个飞机从同一个地方同时起飞,直线相反方向而行.一架飞机的平均速度比另外一架快18公里/小时.1.5小时候,他们相距1179公里,问两架飞机的速度分别是多少.[(x+18)+x]*1.5=1179 算出 x=384,所以两架飞机速度分别是384公里/小时 和 402公里/小时.
1一个垂直的竹杆18米高被风吹倒
茎是垂向地面,,这样它的尖总离树根部6米。
茎是倒下多少米?
嗯,答案应该是10吧
有两架飞机在同一地点往反方向起飞(直线飞行)。一架飞机的平均时速比另一架快18km/h(每小时18公里),请在两飞机相离1179公里,历经1.5小时的时候,算出两架飞机的速度。
希望有帮助XD~
竹子长18米,折了,之后折的一半搭拉到地上,相当于一个直角三角形,地面那边长6米,竹子占两边长18米。设高 X ,(18-x)^2=x^2 6^2, x=8
