I got:

real time vs gain time

2hrs vs 3 mins gain

40hrs vs 60 mins (x20)

960 hrs vs 24 hrs (x24)

= 40 days (divided 960 hrs by 24hrs)

Is this correct please for a?

b) Mrs Warma's watch (also 1 12 hour watch LOSES 5 mins every 2 hours. She also sets her watch to the correct time at noon on 1st January. When will our two watches next show the same time?

I got:

real time vs lose time

2hrs vs 5 mins lose

I am stuck after this....

c) When will our watches next show the same, correct time?

I am stuck with this

Thanks for help in advance.
