There are 20 poles with a constant distance between each pole. A car takes 24 seconds to reach the 12th pole . How much time will it take to reach the last pole?
Choose the correct choice from the following answers
A) 25.25 s	B) 17.45 s	C) 35.75 s	D) 41.45 s	E) None of these
Let the distance between each pole be x m.   Then, the distance up to 12th pole = 11 xm   Speed = 11x⁄24 m/s   Time taken to covers the total distance of 19x   = 19x×24/11x=41.45s   Answer 41.45 s
