Question

A Ferris wheel is 40 meters in diameter and boarded from a platform that is 2 meters above the ground. The six o'clock position on the Ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 5 minutes.
How many minutes of the ride are spent higher than 35 meters above the ground?

Answer 1

Answer:

t >.696 minute

Step-by-step explanation:

Given,   r = 40 m

$p=2\pi r$

$p=80\pi$

Given,     t = 5 min for one revolution

$v=p/t$

$80\pi /5= 16\pi$

time to reach to more than 35 m

$35< 16\pi t$

$t> 35/16\pi$

$t> .696 min$
