Two Clocks

This problem needed a great deal of logical thinking. Excellent solutions were sent in by Zartasha from St Mary's C of E High School, Bryan from The British School of Guangzhou, Aporva from Brackensdale Junior and James B, James H, Jack W and Jack H from Tunbury Primary School. Remember that we like to hear the reasons for your answers, not just the answers.

The group of boys from Tunbury wrote:

Clock B is showing midday because midday is $12$ o'clock and the hand is pointing at $12$.
Clock D is showing the time when Sam gets up. Sam gets up at $7.20$ am (or thereabouts, perhaps $7.15$ am) because the other clocks would make him too late for school.
A shows when he goes to school because D is when you get up and get ready and $8.30$ am is roughly the time that you go to school. The other times are too early or too late.
Clock C shows that Sam turns out his light at $9.40$ pm (again, some of you thought this might be $9.45$ pm which is fine) .

Julie ran home from school on Friday because it took her $30$ minutes .
She stopped to buy some sweets on Monday because she got home at $10$ past $4$.
Julie stayed at school to practise with the band on Thursday because she got home at $10$ to $5$.
She stayed to play with Sam on Tuesday because she got home at $25$ to $5$.
Her teacher held the class in on Wednesday because she got home at $5$ past $4$.

Bryan from The British School of Guangzhou also sent in a clearly-reasoned solution for Julie's clock:

Well done all of you!
