A man,whose walking speed is 15 km/hr on escalator and escalator is being fixed to 30 km and it is moving horizontally with the velocity of 25km/hr and a man has to take his watch. so, find The time taken by that person to reach his destination (in km/hr) is

• distance is 30km.... speed = 25-15=10km/hr...time 30/10=3 hrs

• here velocity of man w.r.t escalator = 15km/hr
  velocity of escalator w.r.t earth = 25km/hr
  so velocity of man w.r.t earth = 15 +25 = 40km/hr
  so time required to take his watch = 30km/(40km/hr) = 3/4 hour = 45 minutes
