[計量] Two cyclists are moving towards each
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?
