英语翻译
the distance to the nearest 100 000km from Earth to the moon is given as 400 000km.The average speed to the nearest 500km/h of a rocket to the moon is given sa 3500km/h .calculate the greatest and least time it could take the rocket to reach the moon

给定地球倒月亮的距离是400000km(精确到100000km),给定火箭平均速度为3500km/h(精确到500km/h),计算火箭到达月亮的时间的最大值和最小值

least: 100000÷3500=28.57h
greatest:400000÷500=800h

地球到月球的距离精确到100000KM/H大约是400000KM/H,而登月火箭的平均速度精确到500KM/H大约是3500KM/H,请计算火箭到达月球的最大和最小可能时间.
(什么sx题目,大概是考四舍五入)
