A person starts walking at a speed of 5km/hr through half the distance, rest of the distance he
covers with aspeed 4km/hr. Total time of travel is 6 hours. What is the maximum distance he
can cover?  Choose the correct choice.
A) 20km	B) 40km	C) 60km	D) 80km	E) 26.6km
t=d/s, so   6=x/2*1/5+x/2*1/4(because half distance with 5 km/ph, and remaining half with 4km/hr)   6=x(18/80)   x=26.6km   ANSW26.6kmR:26.6km
