I have an old alarm clock, on which the hands move at only 95% of the speed that they should do. I need it to wake me up at 7.30 am, so every night, at 10.30pm, I change the time shown on the

clock so that it will show the correct time at 7.30 am when the alarm goes off.

(a) What time does the clock show at 10.30 pm, immediately before I change it?

(b) What time do I change it to?

Please help immediately!!!
