A train departed Singapore at 10.40 a.m.and arrived in Malacca,250 km away,at 2.00 p.m..Alone the way,itmade 5 stops of 10 minutes each.Albert left Singapore in his car at the same time as the train and arrived in Malacca also at the same time but without stopping,How much faster was the train's average speed compared to that of Albert's car.
一辆火车上午10:40离开Singapore,下午2点到达250公里之外的Malacca,在路上,它共停了5站,第站停10分钟.Albert 开车离开 Singapore 的时间与火车相同,到达Malacca 的时间也与之相同,但路上没有停.请问,与Albert的汽车相比,火车的平均速度快多少?
火车的运行时间是3小时20分,减去停的50分钟,实际用时2.5小时,用两地之间的距离250公里除以2.5小时,得出火车的速度为100公里每小时;用250除以3小时20分,得出汽车的速度为75公里每小时.所以火车比汽车的速度快25公里每小时.
