3) We need to find the speed using the below formula:-
Speed = 
Plugging the values of Distance and Time taken into the formula, we get
Speed = 
= 10.416 m/secs
4) Upon rounding it to the nearest hundredth, we get
Speed = 10.42 m/secs

The percentage of births that occurred among women between the ages of 40 and 42 is 26.41%
<h3>Calculations and Parameters</h3>
First, we would add up the ages of the mothers
27 +98+239+326+389+436+468+490+460+387+286+180+102+48+19+5+1
= 3961
Thus, to find the percentage of births occurring among women between the ages of 40 and 42 was:
102+48=150
3961/150= 26.41%
