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 36 hours. What is the maximum distance he
can cover?
Choose the correct choice
A) 20km	B) 40km	C) 60km	D) 80km	E) 160km
t=d/s, so   36=x/2*1/5+x/2*1/4(because half distance with 5 km/ph, and remaining half with 4km/hr)   36=x(18/80)   x=160km   ANSW160kmR:160km
