An antique clock takes 5.5 seconds to chime at 3 o'clock. How long does it take to chime at 9 o'clock ?

5.5/2= 2.75x8=22seconds

looks good to me.

I think it is correct

check good it bad hahahaha

joking its good

To calculate how long it takes for the antique clock to chime at 9 o'clock, we need to consider the distance between 3 o'clock and 9 o'clock on the clock face.

The distance between 3 and 9 o'clock is 6 hours. Since there are 12 hours on a clock, 6 hours is half the distance around the clock face.

Now, let's use the information given: the antique clock takes 5.5 seconds to chime at 3 o'clock.

Since the distance between 3 and 9 o'clock is half the distance around the clock face, we can divide the 5.5 seconds by 2 to find out how long it takes the clock to chime at 6 o'clock, which is halfway between 3 and 9 o'clock.

5.5 seconds divided by 2 equals 2.75 seconds.

Now, since the distance between 6 and 9 o'clock is a third of the distance between 3 and 9 o'clock, we can multiply the time it takes the clock to chime at 6 o'clock (2.75 seconds) by 3 to find out how long it takes the clock to chime at 9 o'clock.

2.75 seconds multiplied by 3 equals 8.25 seconds. Therefore, the antique clock takes approximately 8.25 seconds to chime at 9 o'clock.
