<result>D</result>
two cyclist start on a circular track from a given point but in opposite direction with speeds of 7 m / s and 8 m / s. if the circumference of the circle is 360 meters, after what time will they meet at the starting point?
divide(360, add(8, 7))
"they meet every 360 / 7 + 8 = 24 sec answer is d"
