Question

You go to a Halloween fair with a big Ferris wheel. The wheel has ten seats, and two people are placed on each seat. Every minute a seat passes by the exit platform. At 11 a.m. the Ferris wheel opens for 30 minutes. After fifteen minutes, the wheel doubles its speed - how many people have ridden the wheel during this time ?

Answer 1

Step-by-step explanation:

I hope it's 20 members because the ferris wheel is having 10 seats and 2 people are placed on each seat. So, I done 10*2=20

Answer 2

OK it's an easy one !

Every minute a seat passed so for first 15 minutes = 15 * 2 = 30 people

Now ,

for the next 15 minutes the speed doubled

So now,

two seat passed every minute

So for the next 15 minutes 15 * 2 * 2= 60 people

Overall 30 + 60 = 90 people
