1given: d/t=30,
d/T=??
given: 2d/(t+T)=60.
(1/2)(1+T/t)=1/2
what to do now???
if a particle covers half of distance with 30m/s. Then what should be the velocity of particle at other half distance,so that its average velocity will be 60m/s.

1057these kind of problems are solved in this manner..
let the total distance be d and the speed at the other half distance be x...
then av.velocity=total distancetotal time
now here total time will be d30+dx and total distance 2d..
ATP,
60=2dd30+dx
rearranging, we get...
2+60x=2
thus x becomes infinity here.....hence the trip is not possible as mr.john cena said.....
mr.johncena.....anyway....gud luck fighting with THE ROCK at wrestlemania.. :P
1oh....thanx ketan.....
But actually i don't like this fight ...because my second favourite is THE ROCK itself ....
And there is only a <40% chance that they make JOHNCENA win...
but JOHNCENA will surely win if it was an 'i quit' match....:)
