Explanation:
The "speed made good" is the product of the speed and the cosine of the angle between the direction of the speed and the direction of interest. A change in height is accomplished by speed in the vertical direction.
When a spot on the Ferris Wheel is traveling vertically, as at a side position, the angle difference is zero and the cosine is a maximum. All of the vertical speed results in a change in height.
When a spot on the Ferris Wheel is traveling horizontally, as at a top or bottom position, the angle difference from the vertical is 90°, and the cosine of the angle is 0. That is, none of the horizontal speed results in a change in height.
The vertical speed is not constant because the angle of the direction of motion with respect to the vertical is not constant.
The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.
Addition and multiplication
So for this, multiply both sides by 9, and your answer will be:
