At a local fair, a roller coaster takes 19.63 seconds to complete one ride. If six people can ride at the same time, use estimation to determine how many people can ride the roller coaster in one hour.

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
