## Read the story

The movie starts at 3:45 and ends at 5:20. How long is it?

We jump along the time line: to 4 o'clock is 15 minutes.

From 4 o'clock to 5:20 is 80 minutes. Together that's 95 minutes.

**A trip lasts from 2:50 to 4:10. How many minutes is that?**

## Answer and working

Correct! 10 minutes to 3 o'clock, then 70 minutes. That's 80 minutes.

`10 + 70 = 80`
