A wheel has a diameter of x inches and a second wheel has a diameter of y inches. The first wheel covers a distance of d feet in 130 revolutions. How many revolutions does the second wheel make in covering d feet?
Choose the correct option
A) 65x+y
B) 130x/y
C) 130x+y
D) 100x-y
E) 130y/x
A wheel covers 2πr distance in one revolution. where r= diameter/2   First wheel covers d feet in 130 rev. =&gt; d= 130* 2π * (x/2)   Second wheel covers d feet in let's say P revolutions; =&gt; d = P* 2π * (y/2)   comparing both equations:-   =&gt; p= (130∗2π∗x/2)/(2π∗y/2)   =&gt; 130x/y   Answer :- 130x/y
