这是一道英语数学题!
By using a stopwatch ,Peter finds that the time taken for a colour printer to print 100 identical documents is 7 minutes 5 seconds ,and the relative error is 1/85 .what is the possible range of time required to print 1 document?优质解答
100个 7min5s =425s 偏差1/85 即425/85=5s 425±5s
故对于1 个 所花时间的范围（range of time）为4.25±0.05s,即4.20s~4.30s.
