Complete Question
Everyone loved the Chocolate eclairs and they all got eaten during the party. Mr Watson friend, James, ate 6/8 of them if there were 16 of the chocolates, how many did James eat?
Answer:
12 chocolates
Step-by-step explanation:

= 6/8 × 16 chocolates
= 12 chocolates
Therefore, James ate 12 chocolates.
1day=24 hours
10 days=240hours
60mins=1hr
30mins=1/2hr
total is 240hr+21hr+0.5hr=261.5hr
