a man decides to travel 80 kilometer in 8 hours partly by foot and partly on a bicycle. if his speed on a foot is 8 km/hr and on bicycle is 16 km/hr what distance would he travel on foot
**
let x=distance traveled by foot
80-x=distance traveled by bicycle
travel time=distance/speed
..
x/8+(80-x)/16=8
LCD:16
2x+80-x=128
x=48
distance traveled on foot=48 km
