the path from p to q is 3 km uphill then 8 km on level ground and the 6 kilometre downhill. A man can walk 1km/ hr uphill , 4km/ hr on level path and 6km / hr down hill. how long will he take to go from p to q and back
Answers
if the man can walk 1km/h the distance from p to uphill is 3 km so if we calculate we can get that the men would take 3 hours to go from p to uphill. now if the man go to walk on the speed of 4 km per hour on a level path, after we divide 8 by 4 we get that the men could cross level part in 2 hours. now if the man could walk by the speed of 60 km per hour downhill if we divide 6 km ( the initial distance from level ground to downhill) by 6 we get that the man could cause the level ground to the point q in 1 hour. now we Plus all the time that the man has taken to go from p to q 3+4+1 = 8hrs now we have to calculate the time which the man would take to go from p to q and then again from q to p so so we double the time that the man is taken to go from p to q which is 8 hours SO2 into 8 is equal to 16 hours. 16 hours is the answer.
