If the first snail traveled the distance in 20 minutes, then the second snail, traveling at twice the rate of speed, would take 20/2=<<20/2=10>>10 minutes to complete the race.
If the third snail raced at five times the speed of the second snail, then it would take the third snail 10/5=<<10/5=2>>2 minutes to race all the way up the sidewalk.
