Question

25 Trent's watch runs at half the speed itshould. In other words, the hands on thewatch move only a half hour when an hourof time has really passed. If Trent sets hiswatch correctly at 8 am, what time will itshow when the real time is 10:30 am.?

Answer 1

Given that Trent's watch runs at half the speed it should run, this implies that

for every hour passed, his watch moves by half an hour.

Hence, for every half-hour passed, Trent's watch moves by 15 minutes.

Hence, when the real time is 10:30 am, Trent's watch will show 9:15 am.
