There are 20 poles with a constant distance between each pole. A car takes 24 s to reach the 12 th pole. How much more time will it take to reach the last pole?

To solve this problem, we first need to determine the time it takes for the car to travel from one pole to the next.

1. We know that the car takes 24 seconds to reach the 12th pole. So, the time taken to travel between each pole is 24 seconds divided by 11 (since the car passes 11 spaces between poles to reach the 12th pole from the 1st).

2. 24 seconds / 11 = approximately 2.18 seconds. This is the time taken to travel from one pole to the next.

3. Now, we need to find out how much more time it will take to reach the last pole (the 20th pole) from the 12th pole. The car needs to travel from the 12th pole to the 20th pole, which means it needs to pass 7 more spaces between poles.

4. So, the time taken to reach the last pole from the 12th pole is 7 (spaces between poles) multiplied by 2.18 seconds (time to travel one space).

5. 7 * 2.18 seconds = approximately 15.26 seconds.

So, it will take approximately 15.26 more seconds for the car to reach the last pole from the 12th pole.
