A man decided to cover a distance of 80km in 8 hrs. He can walk at a speed of 6 km/hr and cycle at 8 km/hr successively. How long will he walk and how long will he cycle ?

• as speed in 80km/8hrs=10 km/hr
  as ques solve through mixture and alligation method
  6 km/hr and 8km/hr
  10km/hr
  10-8 10-6
  2km/hr 4km/hr
  so the ratio is 1:2
  ahd we have to find the distance through walk and through cycle
  1/3*80=26.6km
  2/3*80=53.3km
  this is the ans.

• this question is wrong because.....
  if he want to travel 80 km in 8 hrs i.e(of speed 10 km/ph) ...for this he travel certain distance with speed 6 km/ph them to cover the distance in specified time his next speed must be greater than 10 i.e(80/8) km/ph.....

• total time given 8 hrs...
  cycle distance:X,walk:(80-X)
  total time:X/8..+ (80-X)/6=8
  X=128,
  so the time required to cover the distance by cycle=128/8=====16 hr

• Let walking distance= X km
  And cycling distance=Y km
  So, X+Y=80km-------eqn 1
  y=80-x ......eqn 2
  And
  Time = dis/speed
  8= X/6 + y/8 ----/- eqn 3
  put value of y in equ 3
  after solving....
  
  x= 48 nd y= 32
  this is the ans.

• speed=80/8=10km/h
  we can solve by mixture and allegation
  10-6=4 & 10-8=2 km/h
  so ratio is 2/4 i.e 1:2
  distance through walk=80*1/3=26.6km
  distance through cycle=80-26.6=53.4km or 80*2/3=53.3km

• ans 24 km by walk
  32 km by cycle
  bcz he is asking how long he can.
  so for every two hrs he can travel
  walk + cycle
  6+8 for 2 hrs
  6+8 for 2hrs
  6+8 for 2hrs
  6+8 for 2hrs total 8hrs complt
  at this times total four 6kms and 4 8kms

• f+c=80----->1
  f/6+c/8=8 (i.e total 80 km covered in 8 hrs)
  2f+c=128------>2
  solve 1 and 2
  f=48
  c=32
