Answer / sudheer
first consider downwards: jill comes in 1hr and jack in 3hr. so x is 2hr.
now upwards:let speed of jack be '2p' then speed of jill is 'p'.
now (3/p)-(3/2p)=2 and hence jack speed is 2p= 1.5km/hr.

Answer / guest
Total Journey is 6km, so 3km upwords and 3km Downwords.
Getting Down:
Jill speed is 3kmph. So, he takes an Hour to get down.
Jack speed is 1kmph. So, he takes 3 hours to get down.
So x=2 hrs.
Climbing the hill:
Jack waiting time is x ie, 2 hrs.
So Jack went to top of the hill in 3hrs and Jill in 1hr.
