How do I work out this question?

Answer 1

Answer:

170

Step-by-step explanation:

19 45 - 16 55

For convenience, let's find the lapse from 17 00 till 19 45, it's simple 2 hours and 45 mins.

Now add the 5 mins we neglected (from 16 55 to 17 00).

That's 2 hours and 50 mins

1 hour = 60 mins

2 hours = 120 mins

2 hour 50 mins = 170 minutes
