Answer 4

At 11 a.m. there are 918 people per hour entering the park.
A cashier can help a person in 30 seconds, or 0.5 minute.
That means a cashier helps 2 people per minute, or 120 people per hour.

(918 people/hour) / (120 people/hour) = 7.65

Since it's hard do find 0.65 of a cashier, you need 8 cashiers at 11 a.m.

Good.
A parking lot attendant takes 40 sec per car.
40 sec is 2/3 min
How many 2/3 min intervals are there in an hour?

Answer 16

40?

Answer 17

so 366.3 divided by 40? @mathstudent55

Answer 18

there is 366.3 cars every min so divide by 40min?

Answer 19

No.
In 1 hour there are 60 minutes.
A 2/3 minute period of time is less than a minute, so in 1 hour there must be more periods of 2/3 minute than minutes.
40 cannot be correct. The number has to be more than 60.

1 hour = 60 min
How many minute periods are there in 1 hour?
60 minutes/1 minute = 60

How many 2/3 minute periods are there in an hour?
60 minutes/(2/3 minute) = ?

Answer 20

i got 40 again
