The first time Ferguson completed a drill on the decimals he took 56.04 s to get them all correct. He repeated the process over and over again until his best time was 38.48 s. How many seconds faster was his best time than his first attempt?
+309 Answer: \(17.56\)
Solution:
I believe that this is just the subtraction of 38.48 from 56.04.
\(56.04-38.48=17.56\)
