Question

某林場(chǎng)有甲、乙兩個(gè)造林隊(duì)．已知甲隊(duì)每天比乙隊(duì)多植樹5棵，甲隊(duì)植樹100棵與乙隊(duì)植樹80棵所用的時(shí)間相等．若設(shè)甲隊(duì)每天植樹x棵，依據(jù)題意列出的方程是

1. A.
   
2. B.
   
3. C.
   
4. D.
   

Answer 1

D
分析：甲隊(duì)每天植樹x棵，則乙隊(duì)每天植（x-5）棵，根據(jù)關(guān)鍵語(yǔ)句“甲隊(duì)植樹100棵與乙隊(duì)植樹80棵所用的時(shí)間相等”可列方程．
解答：甲隊(duì)每天植樹x棵，則乙隊(duì)每天植（x-5）棵，
甲隊(duì)植樹100棵的所用的時(shí)間為：天；
乙隊(duì)植樹80棵所用的時(shí)間為天，
=，
故選：D．
點(diǎn)評(píng)：此題主要考查了實(shí)際問(wèn)題抽象出分式方程，由實(shí)際問(wèn)題抽象出分式方程的關(guān)鍵是分析題意找出相等關(guān)系．
