  • Question
  • The respective ratio between the speed of a bike, a van and lorry is 3 : 5 : 2. The speed of the van is 250 percent of the speed of the lorry which covers 360 km in 12 hours. What is the average speed of the bike and the van together?


  • Options
  • A. 60 kmph
  • B. 62 kmph
  • C. 64 kmph
  • D. 63 kmph

  • Correct Answer
  • 60 kmph 

    Explanation

    Speed of lorry = 360 12 = 30 kmph

    Speed of van = 250 100   x   30 = 75 kmph

    Speed of bike = 3 5   x   75 = 45 kmph

    Therefore, now required average speed of bike and van  = 75   +   45 2 = 60 kmph.
