做一道英文应用题
The road from home to school has six hundred and thirty meters far.Kitty walks at four point two kilometers per hour.She leaves home at five to seven.Ask:when does she arrive at school?(过程和式子用数字,答句用英文)
答
从家到学校有630米,Kitty 的速度为4.2千米一小时,他7点差5分(其实是6点55分)离开家,问她几点到学校.
4200米=4.2千米
(4200米)/(60分钟/小时) = 70米/分钟
(630米)/(70米/分钟)= 9 分钟
She got back to school at 7:04.
