A software engineer starts from home at 3pm for every walk on a route which has level road for some distance and a then a hillock.he walks speed of 4kmph on level ground and then at a speed of 3kmph on the uphill and then down the hill at a speed of6kmph to the level ground and then at a speed of 4kmph to the home if he reaches home at 9pm.what is the distance one way of his route?  Select the correct option:  A) 12km  B) 15km  C) 18km  D) 24km  E) Data Inadequate
time=distance/speed   so,   let the distance to the level road from home be x km   and the distance to the hillock from the level road be y km   so, (x/4+y/3)+(y/6+x/4)=6   x+y=12 km.   12kmNSWER:12km
