Itâs also easy to accidentally go over the speed limit when you are travelling down a steep hill. Remember to change down a gear to let your engine shoulder some of the braking. If you are moving from a 50mph zone to a 30mph zone remember that you need to be slowed down to 30mph by the time you reach the 30mph sign. If you are moving from a 30mph zone to a 50mph zone, donât speed up before you reach the 50mph sign.
Although two children remains the most common family size, the average number of children per family in the UK has dropped-from 2.0 in 1971 to 1.8. WHERE FAMILIES LIVE.
Then say that 20% of the 18-year-olds had a baby, 40% of the 19-year-olds, 50% of the 20-year-olds, and 30% of the 21-year-olds. Adding these up gives 140%, so the average woman in this hypothetical society has 1.4 children in her lifetime. Of course in real life women women are typically having children from ages 17 or 18 up to their 30's, and some have children even younger or older, so there are a lot more than four numbers to add together.
