Find the average speed, if a man travels at a speed of 24kmph up and 36kmph down at an altitude of
200m.

• Here in this ques altitude 200m is a dummy part. av. speed=2*36*24/(36+24)=28.8 kmph
• 9 years agoHelpfull: Yes(26) No(2)
• avg speed = 2xy(x+y)= 28.8 kmph
• 9 years agoHelpfull: Yes(4) No(3)
• Average speed= Total distance/ Total time taken= (200+200)/((200/24)+(200/36))
  =28.8 kmph

• H.P of 24,36 = (2*36*24/(36+24))
  = 28.8 kmph

• Using the formula 2xy/x+y

• there is nothing to do with 200m . and average is 2*24*36/(24+36) = 28.8km/h
• 9 years agoHelpfull: Yes(0) No(0)
• avg spee=2xy/(x+y)
  x=24kmph
  y=36kmph
  => avg speed=28.8kmph

  total distance / total time
• 9 years agoHelpfull: Yes(0) No(4)
• 2*s1*s2/(s1+s2)
  =2*24*36/(24+36)
  =28.8kmph
