Infosys Company Numerical Ability Time Distance and Speed

A man walks at 4 km/hr on plain, then at 3 km/hr uphill and then returns through the same road at 6 km/hr downhill and at 4 km/hr on the plain. It takes altogether 6 hours. So what distance he covered in one way?

Read Solution (Total 3)

Let the distance covered one way on plain be x ,uphill be y

time = distance travelled/speed
x/4 + y/3 + y/6 + x/4 = 6
x/2 + y/2 = 6
x+y=12

Let plain road=x km
Hill road=y km

x/4+y/3+y/6+x/4=6
by solving these
x/2+y/2=6
x+y=12
