    Three cars leave A for B in equal time intervals. They reach B simultaneously and then leave for Point C which is 240 km away from B. The first car arrives at C an hour after the second car. The third car, having reached C, immediately turns back and heads towards B. The first and the third car meet a point that is 80 km away from C. What is the difference between the speed of the first and the third car?

    If we can only count no. Of steps when escalator is switched off , then why do we even consider the speed of escalator?
    Referring to the very first example
    We should only consider our speed which is 2 steps per second.
    At some point u are saying escalator is moving, but also u said we can count N only when escalator is switched off?

    • @AshishPal-sh2yo
      @AshishPal-sh2yo 4 года назад +1

      When escalator is switched off then number of steps will be the product of speed of person and time taken only , but when there is relative motion we need to consider both the speeds of person as well escalator . In the very first example speed of man and escalator added up, hence it becomes the total speed
      Hope you get it :)

      But ultimately we are here calculating no. Of steps only
      And he mentioned the we can calculate no of steps only when the escalator is switched off.
      Then how come we are also considering the case when escalator is also moving at certain speed?

      @AshishPal-sh2yo 4 года назад +4

      @@gametutorial2942 I don't think so we can calculate number of steps when we're given relative speeds , he said number of steps will be constant when escalator is switched off. Ultimately we can't calculate number of steps when we've given relative speeds we can't put escalator on rest.

      There is a difference between Escalator's total no of steps and the speed of the escalator, sir never took no of steps of a escalator while moving, he took the speed of the escalator.

    • @mohitpandey6228
      @mohitpandey6228 2 года назад +1

      cause you see the person is moving 11 steps and the escalator is moving 2steps/sec = 70 steps even if it is turned off the person has to climb his step + the steps which was previously covered by the escalator so in a turned off state a person has to climb 81 steps....just relate as if you are onto the escalator and the questions become elegant
