A travels from B to C a distance of 250 miles in 5.5 hours. He returns to B in 4 hours 40 minutes. His average speed is ?

  • a
  • b
  • c
  • d
  • OOPS, your answer is incorrect

    Total distance = 250 + 250 = 500 miles

    Total time = 5 hr 30 min + 4 hr 40 min = 10 hr 10 min = 10 (1/6)

    Speed = distance / time

    Speed = 500 / 10(1/6) = 3000 / 61

    Average speed = 49.18 ≈ 50

Walking at the rate of 4 kmph a man cover certain distance in 2hr 45 min. Running at a speed of 16.5 kmph the man will cover the same distance in ?

  • a
  • b
  • c
  • d
  • OOPS, your answer is incorrect

    From the problem we understand that the distance is same in both scenarios. Only speed and time vary.

    While walking, distance1 = speed1 x time1

    While running, distance2 = speed2 x time2

    distance1 = distance2

    speed1 x time1 = speed2 x time2

    4 x 2 hr 45 min = 16.5 x time2

    4 x 165 = 16.5 x time2 (Changing time in minutes)

    time2 = 40 min.

  • a
  • b
  • c
