It is given that at a local fair, a roller coaster takes 19.63 seconds to complete one ride
six people can ride at the same time
one hour=60 minute
1 minute= 60 second
therefore, one hour = 3600 sec
therefor no of people who can ride the roller coaster in one hour=3600*6/19.63=1100 people
therefore 1100 is the answer
