Question

DESPERATELY NEED HELP ON THIS PLEASE! X(
The London Eye is a Ferris wheel in London, England, that travels at a speed of 0.26 meter per second. How many minutes does it take the London Eye to complete one full revolution? Round your answer to the nearest hundredth. The radius is 67.5m.

Answer 1

Answer:

27.19 Minutes

Step-by-step explanation:

So the Circumference is C = 2$\pi$r

C = 2·$\pi$·67.5 (the radius)

C ≈ 424.12 metres (rounded to nearest hundredth)

Then you take 424.12 metres and divide it by 0.26 metres (because it is 0.26 metres per seconds) (I like to make this weird table, I don't know how to describe it, you could do it like: $\frac{424.12 metres (times) 1 second}{0.26 metres}$ (I learned this table from chem, so let me know if you know what kind of table I'm talking about... Its a conversion table...)

The metres cancel out and you end with seconds

You end up getting 1631.23 (rounded to nearest hundredth) seconds. Divide that by 60 (seconds) and you'll get 27.19 (rounded to nearest hundredth) minutes

Answer 2

The minutes take the London Eye to complete one full revolution is 27.19 minutes.

We have given that the radius is 67.5m

What is the circumference of the circle?

The circumference is,

$C = 2\pi r$

$C = 2\times 3.14\times 67.5$

$C \approx 424.12 metres$

Now next we have to divide the circumference by speed

So we get,

$T=\frac{424.12m}{0.26\frac{m}{second} } \\\\T=\frac{424.12m}{0.26} \times \frac{second}{meter}$

Meter term is on the nemorator as well as dinominator so cancel It.

$T=1631.23 seconds$

1min=60seconds

Divide 1631.23 by 60 we will get time in minutes

$T=27.19 minutes$

Therefore,the minutes take the London Eye to complete one full revolution is 27.19 minutes.
