simple

Step-by-step explanation:

if it starts at 11 and runs for 30 minutes and every minute a seat passes 30 seats would pass and every seat has 2 people so 30 * 2 = 60 people have ridden the ferris wheel

Mary Andrade · Answer 2

The wheel has ten seats, and two people are placed on each seat.

Every minute a seat passes by the exit platform.

So, one ride takes 10 minutes.

At 11 a. m. the Ferris wheel opens for 30 minutes.

The first two people start their ride at 11 a. m. and the last two people start their ride 10 minutes before the end, that is at 11:20 a. m.

How many people have ridden the wheel during this time?

So, from 11 a. m. to 11:20 a. m. only 21 pairs of people will be able to take their seats.

That brings the full number of people having a 10-minute ride during 30 minutes to 42.
