Question:medium
Anora sees the time on her perfectly working ordinary wrist watch at 10:20 AM on 8th of March, 2025 and the next occasion when she sees the time on her same watch is at 11:15 AM on 11th of March,
2025. Determine the number of times, the hour and minute hand of her watch would have been exactly over one another between the two times that Anora saw the time on her watch?

Show Hint
The hands of a clock coincide 11 times in every 12-hour period. Use this to calculate the number of coincidences over a given time interval.
