Matthew and Chloe both started
their work at the same time. Who finished later?
Underneath the question, we can see
a picture of Matthew and Chloe. And both speech bubbles tell us the
times that they finish their work. Let’s look at them one by one. If we look at the minute hand,
which is the long hand on Matthew’s clock, we can see that it’s pointing straight
down to the number six. We know that when a minute hand
points straight up, it’s an o’clock time. And if it’s turned to point to the
number six, we know that it’s made half a turn around the clock. The time must be half past
something, but half past what? Let’s look at the hour hand to find
out.
The hour hand on Matthew’s clock,
which is the shorter hand, isn’t pointing at any numbers. In fact, it’s halfway in between
the four and the five. Do you think that means it’s half
past four or half past five? Well, if we think of the direction
that hands move on a clock, we know that it’s gone past the four, but it hasn’t
quite reached the number five yet. The time is half past four. Now, let’s see what time Chloe
finished her work.
The minute hand on Chloe’s clock is
pointing to the 12. This is an o’clock time. And if we look at the hour hand,
it’s pointing to the four. Chloe finished her work at four
o’clock. Now, our question asks us, who
finished later? Which time comes after the other,
half past four or four o’clock? Well, as we’ve said already, four
o’clock comes first. And the dotted line that we drew on
Matthew’s clock shows us that half past four comes when the minute hand has gone
half the way around the clock. Matthew finished working after
Chloe. Matthew finished later.
