In this 11-plus Maths quiz, you'll do a few calculations involving different measures of time. Spend some time reading the questions carefully and see if you can get 10 out of 10. You should do the previous quizzes before you do this quiz.
Just as we have words to describe large amounts of time, we also have words for very small amounts of time. You might think that a second is the tiniest amount of time, but you'd be wrong. There are milliseconds, microseconds and even nanoseconds. Do you know what the smallest measurable unit of time is called? It's called Planck time, named after the German physicist Max Planck.
Anyway, you won't be learning about such extremes of times in your 11-plus, so let's concentrate on this quiz.
