  • Question
  • A Bus is running at 9/10 of its own speed reached a place in 22 hours. How much time could be saved if the bus would run at its own speed ?


  • Options
  • A. 1.5 hrs
  • B. 1.7 hrs
  • C. 2.2 hrs
  • D. 3.5 hrs

  • Correct Answer
  • 2.2 hrs 

    Explanation

    Let the original Speed be "s" kmph
    And the usual time be "t" hrs
    Given that if the bus is running at 9s/10 kmph the time is 22 hrs
    => [9s/10] x 22 = t x s
    => 99/5 = t
    => t = 19.8 hrs

     

    Hence, if bus runs at its own speed, the time saved = 22 - 19.8 = 2.2 hrs.
