Even without looking up the very public ADS-B data, you are ignoring the fact that ARFF trucks are very much not the same as the average firefighting truck as well as the fact that the CRJ-900 was in the middle of its landing roll (which alone would have been clue enough that it was obviously moving much faster than 24mph).
