Recent reports have suggested that sportsmen with decreased metabolic rates perform
better in certain sports. After reading one such report, Jordan, a sportsperson from Arlington
decides to undergo a rigorous physical training program for 3 months, where he performs
Yoga for 3 hours, walks for 2 hours and swims for 1 hour each day. He says: I began my
training on a Wednesday in a prime number month of 2008. I lost 1% of my original weight
within the first 30 days. In the next two months combined, I lost 1 Kg. If he walks at 5 mph
over a certain journey and walks back over the same route at 7 mph at an altitude of 200
meters, what is his average speed for the journey?
(a) 5.83
(b) 2.92
(c) 6.00
(d) 35.00

• (2*5*7)/(5+7)==5.83

• when you have this type of Qs...be clear what is your options...
  
  see in this example values never reach 2.92 or 35.00 ... so ans must be 5.83 or 6.00
  now we have an equation like 2ab/(a+b) which gives you the avg. speed over the same distance...
  
  here 5.83 is an answer...

• avg speed = 2ab/a=b
  = 2*7*5/7+5
  =5.83
