At midnight on Sunday 31st December, Professor Stone sets two of his analogue clocks to the correct time.
One of his clocks gains one minute every hour and the other loses two minutes every hour.
1. When will the clocks next show the same time as each other?
2. When will the clocks both show the correct time?
This is driving me mad! Is there an easy way to work it out? Any help appreciated! Muzz
After the first hour there will be a difference of 3 minutes between the clocks. After 20 hours there will be a difference of one hour. After 240 hours( 10 days) they will show the same time.
The clock that is losing one minute each hour will be 4 hours slow when it shows the same time as the other one.
It would take another twenty days until it was showing the correct time.
Avatar - just back in and thought I'd look at this again! Yes, we got there in the end! I think I'll stick to the general knowledge crosswords - MUCH easier!
Thanks again to all for your help and wisdom, Muzz
