Question

KFC店每天營(yíng)業(yè)時(shí)間是

14

小時(shí)．

Answer 1

分析：首先把普通計(jì)時(shí)法化成24時(shí)計(jì)時(shí)法，上午時(shí)刻不變，晚上時(shí)刻加12時(shí)；然后求營(yíng)業(yè)時(shí)間=結(jié)束營(yíng)業(yè)時(shí)刻-開(kāi)始營(yíng)業(yè)時(shí)刻；即可得解．

解答：解：11時(shí)+12時(shí)=23時(shí)，
23時(shí)-9時(shí)=14時(shí)，
答：KFC店每天營(yíng)業(yè)時(shí)間是14小時(shí)．
故答案為：14．

點(diǎn)評(píng)：此題主要考查了時(shí)間的推算，營(yíng)業(yè)時(shí)間=結(jié)束營(yíng)業(yè)時(shí)刻-開(kāi)始營(yíng)業(yè)時(shí)刻，要注意：把普通計(jì)時(shí)法化成24時(shí)計(jì)時(shí)法．
