What will be the measurement of the angle made by the hour and minute hands of a clock when the time is 'quarter past 3'?

​At what time between 7 and 8 o'clock will the hands of a clock be in the same straight line but, not together ?

​A watch showed five past five on Wednesday evening when the correct time was 5:00 p.m. It loses uniformly, and was 5 minutes slow after two days at 7:00 p.m. When did the watch show the correct time ?​
