Have a go at writing each of the questions in a mathematical
form. Look at this example question to see what I mean.
The film was 3 hours long, give or take 15 minutes.
So the film could have been anything between 2 hours 45 minutes
long (take away 15 minutes from 3 hours) or 3 hours 15 minutes (add 15 minutes
to three hours).
We can write this as:
2 hours 45 minutes ____ the length
of the film ____ 3 hours 15 minutes
