A person starts walking at a speed of 5km/hr through half the distance, rest of the distance he
covers with aspeed 2km/hr. Total time of travel is 9 hours. What is the maximum distance he
can cover?  Choose the correct choice from the following answers
A) 20km	B) 40km	C) 60km	D) 80km	E) 90km
t=d/s, so   9=x/2*1/5+x/2*1/2(because half distance with 5 km/ph, and remaining half with 2km/hr)   9=x(18/40)   x=20km   20kmNSWER:20km
