It is 9 o’clock. Pick the time it was one hour
ago. Was it 8 o’clock, 9 o’clock, or 10
o’clock?
We’re shown two different
clocks. This clock shows 9 o’clock. We have to work out what time it
was one hour ago. So, we need to work out what the
time was an hour before 9 o’clock. The hour before 9 o’clock is 8
o’clock. We know that nine take away one is
eight. So, 9 o’clock take away one hour is
8 o’clock. Which of our three clocks shows
this? It’s the first clock. If it’s 9 o’clock now, then the
time one hour ago was 8 o’clock.
