Next week, the children will focus on solving problems involving converting between units of time.

# Time problems

Follow these tips when solving time problems:

- If some of the times in the problem are in seconds, some in minutes and some in hours, change some of them so they are either
**all** in seconds, **all** in minutes or **all** in hours.
- When reading timetables, make sure you know what type of information is in each column and row.

## Example 1

How long does it take for the 11.55 train from Normington to get to Kirkfield?

(The empty space in the table means the 10:39 train from Normington doesn’t stop at Baskwell.)

Look along the Normington row until you reach the column that starts with the 11.55.

Look down that column until you get to Kirkfield and read off the time, 12.44.

Now you need to find the difference between 11.55 and 12.44. A good way to do this is to break up the time into smaller units within each hour.

5 + 44 = 49 minutes.

So the 11.55 train from Normington takes 49 minutes to get to Kirkfield.

## Example 2

Sammy wakes up at 7.00am. He eats his breakfast at 7.30am and sets off for school at 8.30am. School starts at 9.00am.

First break is at 10.30am and by 12.00pm in the afternoon he is ready for lunch. School finishes at 3.30pm when Sammy is picked up by his Dad. He eats tea at 5.00pm and then leaves for football practice, which starts at 6.00pm.

When he gets home at 7.30pm, he has a bath and a snack, making his way up to bed at 8.30pm so he is bright and fresh for school in the morning.
