前十分钟他走了全程的百分之四十,接下的十分钟他走了剩下的百分之六十.前十分钟和后十分钟的哪个更快一些

我觉得选取文章的一个方面好一点

1/2-2/9=5/18
300/5/18=1080
或者
设总字数为
前十分钟打了2/9x个字
加上300就等于1/2x
算出x.x=1080
2/9x+300=1/2x
300=1/2x-2/9x
300=9x/18-4/18x
300=9x-4x/18
300=5x/18
5x=18*300
5x=5400
x=1080

可以假设全程是100米.前十分钟走了全程的百分之四十,就是四十米.后十分钟走了剩下路程的百分之六十,就是三十六米.所以前十分钟走的快.

剩下的字数：总字数=7:9=9分之7
9分之7-2分之1=18分之5
300/18分之5=1080
答：一共有1080个字

百度

前10分钟路程10*1/6=5/3 km
剩下 3-5/3=4/3 km
剩下的时间 4/3 / 2/9 =6分钟

前十分钟打了240字,总字数1080

Good morning everybody,It's really my great honor to be here to give

A monkey and a cat went to the cinema last week.They had a big breakfast.They went there by bus.But when they got there,they were really disappointed——There were no more ticket for the film they wanted to see!They had a good idea:They went to the home of rabbit,and played with the rabbit.But rabbit’s mum didn’t let them to play,because her just cleaned the room.Oh!What a terrible day!The cat and the monkey can’t play today,they are crying now.
So much for this ,thank you!
