It is 25 minutes after 9. Pick the time it will be in 10
minutes. 9:15, 9:30, or 9:35.
In this question, we’re being asked
to find the end time, in other words, the time that it’s going to be. And to help us, we’re told the time
that it is now, which is 25 minutes after 9, and also the duration or the time
that’s going to go by, which is 10 minutes. So, we’re being asked if it’s 25
past 9 now, what will the clock look like in another 10 minutes time? Let’s sketch some clocks to help us
here.
We know that when the time is 25
minutes after nine, the minute hand points to the number five and the hour hand is
almost halfway between the numbers nine and 10. This is our start time, and we also
know the time that goes by or the duration. The minute hand is pointing to the
number five, but 10 minutes need to go by. Remember, the gap between two
numbers that are next door to each other on a clock face is five minutes. So, we can skip count in fives to
count 10 minutes. Five, 10. After 10 minutes have gone by, the
minute hand is going to move so that it is pointing to the number seven.
Now, we know the end time we’re
looking for. The minute hand is going to be
pointing to the seven. And because it’s just past half
past nine, we’d expect the hour hand to be just a little bit more than halfway
between nine and 10. And if we look at our answers, we
can see that only one of the clocks looks the way we wanted to. It’s this one, isn’t it? We know that 25 plus 10 is 35. And so, 9:25 plus 10 minutes is
9:35. The time that it will be in 10
minutes is 9:35.
