The London Eye (a ferris wheel) makes one rotation in approximately 30 minutes. What is the measure of the angle (in degrees) that a cart (spoke on the wheel) will rotate in 12 minutes?

Question

precal · Answer

well not sure I can do this one but let's give it a go

precal · Answer

In 15 minutes it would go half the distance or half of a rotation.  A rotation is 360 degrees so half of it is 180 degrees

precal · Answer

so we know that it has to be less than 180 degrees

anonymous · Answer

so straight to the point , what is the final answer of this question?

precal · Answer

well that is it, I have to think it out

precal · Answer

I can't just look at a math problem and just state a solution

anonymous · Answer

ow thank you so much for helping me here right now , im not so sure in my answer here :(

precal · Answer

12/15 is .8 or 80% 
so I am going to guess  180 times .8 = 144 degrees

anonymous · Answer

YES we have the same answer :D

precal · Answer

yes I believe that is true
12/30 is .4 or 40%  
360 times .4 = 144 degrees
