5 km walking, 30 km on the bus. Let w represent the distance traveled on foot, and b represent the distance traveled by bus.
The total distance is 35 km.
w+b=35
The total time is 1.5 hours. Each leg has time equal to distance/speed.
w5+b60=1.5
Multiply by 60 to clear the fractions.
12w+b=90
Subtract the first equation,
11w=9035=55
w=5
b=30
Check:
w5+b60=1+.5
