with early start of car on sunday morning at 6am &with 3and half hrs journey he can travel upto 140 miles .

After picnic at 30 miles /hr he can return back to home in 4.5 hrs.

SO DESTINY SHALL BE 130 TO 140 MILES AWAY TO REACH BACK ON SUNDAY NIGHT.

Can u tell me how you got the ans 120miles.

time=distance/speed, suppose the distance is X.it should be such that total time should not exceed 8  hours.

now the speed is  30 and 40

therefore X/30 + X/40 =8 which gives u X=120 miles

yes the answer is 137.15km ,in case the total time of journey is 8 hours exactly.the distance of the picnic spot shud b less than 137.15 kms.

can anyone confirm me that in this question whether the total time is 8hr or its 8hr per day and which means the total time become 16 hr?

plz i need it before 15th july 2006 my interview is on 16th

if we do in this way

average speed=2xy/x+y

speed=(2*30*40)/30+40

       =34.28m/hr

total time=8

distance=speed *time

           =34.28*8

           =274.28 miles    (its comming different)

and if we consider total time =16 hr

distance =34.28*16

            =548.57 miles

which one is correct m confused ,the way in which the question is written

plz reply soon
