To find the width of each class interval, we need to look for the range of values within each interval.

For the first interval, the range is 24-20 = 4. 
For the second interval, the range is 19-5 = 14. 
For the third interval, the range is 14-10 = 4. 
For the fourth interval, the range is 9-5 = 4.

We can see that the range of values within each interval varies, but the only common factor among them is that they are all multiples of 5. Therefore, the best choice for the width of each class interval is 5.
