#11 Lunar years
My twin sister went to live on the moon
on our 30th birthday. From then on, she
counted a year as 365 sunrises, just as we
do on Earth. I am now 60. Which birthday
did she last celebrate?#12 Hole of the moon
I punched a hole 6 millimetres across in a
piece of paper and held it at arm’s length
to look at the full moon. I was pleased to
find that the moon filled the hole perfectly.
If the moon is 3500 kilometres across, can
you estimate how far away it is?Answers next week#10 Betty’s change
Solution
The smallest amount of change you could
have received is 30 cents. With no nickels,
Betty would have been obliged to give you a
quarter – the largest coin that doesn’t take
her over the amount that she owes you –
and then five pennies (25c+1c+1c+1c+
1c+1c), so six coins in total. She could
have reduced the number of coins to
three by giving you your change in dimes
(10c+10c+10c).1 Neil Armstrong was the
first man to walk on the
