##### Stage: 3 Challenge Level:
Year 3 at How Wood Primary approached this problem in an interesting way:

We tried to work out the problem. We knew we needed to make sensible estimates. To work out Usain Bolt's record, for example, we ran the distance ourselves and found out what times we scored. We thought that he'd be able to do it a little bit faster than us, so that helped make our guesses. Two groups guessed really well with 10 seconds. So we were using what we already know to help us solve a problem.

Fantastic! This is a great way to estimate the kinds of numbers you're looking for and use the data you have sensibly.

The final table of answers, which loads of people got right, is given below. Thanks to everyone for the submissions!
