Question
A man travels some distance at a speed of 15 km/hr and
returns at a speed of 9 km/hr. If the total time taken by him is 2 hrs 40 min, the distance isSolution
Let the distance travelled by a man be D km According to the question, Total time taken = 2 hrs 40 min = 2(40/60) = 8/3 hours Total time = T1 + T2 D/15 + D/9 = 8/3 (3D + 5D)/45 = 8/3 8D/45 = 8/3 D = 15 km
