Question

Why 2 hrs 45 min is written in my answer sheet,I am unable to understand the pattern, pleaseeeeeeeeeeeee help me in understanding it​

Answer 1

Answer:

because starting time when Katrina went to watch movies is 07:15

the end time was 10:00

so the question is time long movie last so on subtracting

10:00

-07:15

1 hour gives to minutes then 1 hour = 60min

and subtract 15 in 60 and 7 in 9 so

2 hour and 45min

B is correct answer
