A bus starts at 6:00 pm. from starting point at d speed if 18m/s. reached its destination. Waited for 40 minutes. And again returned back at the speed of 28m/s. Find the time to reach the destination ?

• suppose distance is x meters
  -> x/18 - 40*60 = x/28
  on solving x = 120960 m
  time = 120960 / 18 = 6720 sec
  = 6720/ 60 = 112 min = 1 h 52 min
  hence ans is 7:52 pm

• time is not equal here .. hence we cant equate

• shivam chugh....plzz explain why u substract
  x/18 - 40*60 = x/28...
  plzz explain

• but the bus is not returning in d same time it travelled to destination.
  so how can we say dat time is equal?

• VAGHANI RUSHI:
  How 18m/s = 5km/hr....this is not correct.
  actually 18*18/5=64.8 km/hr

• suppose distance between source and destination is X
  18 m/s = 5 km/hr
  28 m/s = 70/9 km/hr
  
  -> X/5 - 40 = 9X/70
  -> so u get the value of x=28/3
  
  so your time is X/5-40 or 9X/70 put value of X= 28/3
  and u get 1/3 hr (Ans)

• 18 metre per second is equal to 5 kilometre per hour
  28 metre per second is equal to 70/9 kilometre per hour
  let distance is x km
  for first ride it takes x/5 hrs
  for 2nd ride it takes 9x/70 hrs

• he done that because bus is not running for that 40min . so it is not covering any distance to reach destination>>>>annu priya

• i think this question is incomplete .... we need some details about distance or relation between the time
