here is Lihua report to you.
yesterday afternoon,
about half past five o'clock,
there was a student who was listening mp4 hit another student.
He was totally in his music so that he didn't find the other student at all .
while the other student was concentrating on his cellphone too.
the ends is that they both get hurt.
i think, it too dangerous to pay your attention to other things while you are in a rush hour.
it's not only risks your life but others lives.
so.from now on, let's obey traffic rules and be responsible for ourselves!

dear sam,
i am li hua.i think you can ride a bike tour.
Speed
In just about every town, cycling on a Giatex folding bike is often quicker than other forms of transportation. No car door to unlock, no engine to start or warm up, no seatbelt to put on, no need to stop at a gas station to fuel up, etc. When you arrive, take 10 seconds to fold the bike & place it in a bag to take inside with you. That's door to door transportation free of the frustrating delays you'd experience otherwise.
yours,
li hua
类似问题2：李华骑自行车由甲地到乙地,每分钟行400米,到达乙地后,李华立即返回,每分钟行600米,求李华往返的平均速度.[数学科目]
答案是往返的平均速度是480米.
1、可以假设李华从甲地到乙地用时为A,已知速度为每分钟400米,则甲乙两地之间的距离为400A.那么李华从乙地返回甲地每分钟速度为600米,则用时2/3A.
2、李华从甲乙两地往返的距离为400AX2=800A,用时为A+2/3A,那么往返的平均速度为：800A/(A+2/3A)=480米.
类似问题3：李华骑自行车3/4小时行驶15/2公里.照这样计算,他骑自行车行驶12公里要多少时间?[数学科目]
设每小时骑车x公里!
所以得：
3/4x=15/2
x=10
12除10＝1.2小时

类似问题5：李华骑自行车4分之3小时行驶2分之15千米.照这样计算,她骑自行车行驶12千米需要多少时间?[数学科目]
