1. My watch (which is a 12 hour watch) gains 3 minutes every 2 hours.
a) I set my watch to the correct time at noon on 1st January. If I don't reset it, when will it next show the correct time?
I got 48 hours after, so that's at noon on the 3rd January. as if my watch gains 3 minutes every two hours then over 24 lots of 2 hours, it would have gained an extra 2 hours. So that is 24 lots of 2 hours = 24 x 2 = 48 hours added to the 'correct' starting time of noon. Hence, my answer of noon on the 3rd January.2. Mrs Varma's watch (also a 12 hour watch) loses 5 minutes every 2 hours. She also sets her watch to the correct time at noon on 1st January.
b) When will our two watches next show the same time?
I am completely stuck here :(... please help to explain to me how to do this...3. When will our watches next show the same, CORRECT time?
Again, I can't do this... Any explanation would be greatly appreciated. Thank you.
