javagal,who decided to go to weekend trip should not exceed 8 hr, driving in a day.The average speed of forward journey is 40 mile/hr.Due to traffic on sunday, the return journey average speed is 30mile/hr.Hor far he can select a picnic spot?

• Your answer should be divided with 2 as the question is "how far he can select a picnic spot?".so with total 8 hr of driving he has to come back from picnic spot.
  so the ans is 274.24/2 = 137.12 miles.

• Find the avg speed. Formula is 2XY/(X+Y) = (2*30*40)/(30+40) = 34.28. Now he can travel (34.28)*(8) = 274.24 miles is ans.

• since both Saturday and Sunday are weekend so he he can travel 8+8=16 hrs
  now let he select picnic spot at a distance of x miles
  so, (x/40)+(x/30)=16
  x= 274.2857miles

• No saubhik, i think both Saturday and Sunday are weekends. So he will get total of 16 hrs journey. That is why it is mentioned as "traffic on Sunday".
