You go to a Christmas fair with a big Ferris wheel. The wheel has ten seats, and two people are placed on each seat. Every minut

monitta

60 people have ridden the wheel in 30 minutes

The time is given as:

$Time =30 \minutes$

The number of seats on the wheel is given as:

$Seats = 10\\$

The number of people on a seat is given as:

$People =2$

Every minute a seat exits the platform.

This means that, 2 people exit the platform every minute

So, the number (n) of people that exit the platform after 30 minutes would be:

$n =People \times Time$

This gives

$n = 2\times 30$

Multiply

$n = 60$

Hence, 60 people have ridden the wheel
