Re: [計量] Two cyclists are moving towards each
※ 引述《eadanlin (=口=)》之銘言：
: 印度雞精
: 6. Two cyclists are moving towards each other at 10 miles/hour. When they are
: 50 miles apart, a fly starts from one cyclist and move towards other, moving
: to and fro till the two cyclists meet each other. If the fly is moving at the
: rate of 15 miles/hour, then find the total distance covered by the fly?
: 我算的是36 miles
: 怕大家被我誤導 我先不寫算式好了XDD
: 不曉得有沒有人得到其他的答案?
兩個人2.5小時後會相遇
在這期間那個fly 就是一直在飛
速度保持 15 miles/hour
所以當兩人遇到時 fly飛行的距離就是
15*2.5= 37.5 miles
