this is a +2 physics but it took a while for me to solve it.

here is the solution.

total time take is 6 hrs.

so lets assume x is the plane distance and y is the uphill then the equation is

x/4 + x/4 + y/3 +y/6 = 6

x/2 + y/2 = 6

x+y = 24.

in a hurry I forgot to write it correctly

x+y is 12 but he went to and fro.

so it is 2(x+y) which is 24.

Hi Friends

I have understood in this way.. it might be wrong also...

The Person Starts His walk 3PM back to his destiny 9pm.

He walk for 6hrs.

4km/hr in flat 3km/hr and 6km/hr down the hills.

4+3+6(13km) in 3hrs. so he walked for 6hrs..

he walked for 26km in 6 hrs...

might may be correct or wrong.

regards

Sangeetha

Ans is 25
4+3+6 13 km (in 3 hours)
he reaches in similar speed (4 km) on level ground for another 3 hours (4+4+4 12)
so the ans is 13+12 25km.
