As you ride a ferris wheel, the height you are above ground varies periodically. consider the height of the center of the wheel to be the equilibrium point. suppose the diameter of the ferris wheel is 42 feet and it travels at a rate of 3 revolutions per minute. at the highest point, a seat on the ferris wheel is 46 feet above ground

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
