A roach named Daniel and a donkey named Luke had a bet going to see who was the
fastest. Each agreed to run a 500 m race to see who was the fastest. Luke ran as fast
as he could at a speed of 0.3m/s for the whole race. Daniel, thinking he is so fast, ran
a much different race. Daniel ran the first 100m at 2.2 m/s, then he got tired so he
stopped for some water and to catch his breath, which took 30 minutes. Feeling
refreshed, he ran the last 400 m with an average speed of 2.9 m/s.
