In part d) you have to reject one of the answers. Since the number of parts produced by Factory B has to be a positive number, >0. The denominstor has to be more than 0 as well. Therefore reject x = 0.2212.
For e) use the 3.d.p answer to get an answer with h, mins and secs. To convert 0.105h to mins, multiply it by 60 (since 1h=60mins) and you will get 6.3min. 0.3min to convert to secs, multiply it by 60 again since 1min =60 sec.
Hope this helps! (:
