    The distance between two places A and B is 140 km. First scooter departs from place A to B, at a speed of 50 km/h at 10 am. Second scooter departs from place B to A at a speed of 30 km/h at 12 pm. At what time will both the scooters meet each other

  • 1:50 pm
  • 12:50 pm
  • 1:00pm
  • 01:50 pm
  • 12:30 pm
  • Explanation:

    Distance travelled by the firs scooter in 2 hours 

    = Speed × Time = 50×2= 100km

    Remaining distance = 140-100=40km

    time to meet both scooters = Distance/Relative Speed

    = 40/50+30 = 40/80 = 1/2 hours
