Question

甲乙兩個(gè)修路隊(duì)，甲隊(duì)每天修65米，乙隊(duì)每天修73米，多少天后，甲隊(duì)比乙隊(duì)少修120米？

Answer 1

分析：先求出每天甲隊(duì)比乙隊(duì)少修的路的長(zhǎng)度，再根據(jù)修路的時(shí)間=少修的路的長(zhǎng)度÷每天甲隊(duì)比乙隊(duì)少修的路的長(zhǎng)度即可解答．

解答：解：120÷（73-65），
=120÷8，
=15（天），
答：15天后，甲隊(duì)比乙隊(duì)少修120米．

點(diǎn)評(píng)：等量關(guān)系式：修路的時(shí)間=少修的路的長(zhǎng)度÷每天甲隊(duì)比乙隊(duì)少修的路的長(zhǎng)度是解答本題的依據(jù)，關(guān)鍵是求出每天甲隊(duì)比乙隊(duì)少修的路的長(zhǎng)度．
