Yochanan walked from home to the bus stop at an average speed of 5km/h. He immediately got on his school bus and traveled at an average speed of 60km/h until he got to school. The distance from his home to school is 35 kilometers, and the entire trip took 1.5 hours. How many kilometers did Yochanan cover by walking and how many kilometers did he cover by travelling on the bus?

distance by bus  x km
distance walking  35x km
x/5 + (35x)/60 = 1.5
times 60
12x + 35x = 90
11x = 55
x = 5
he walked 5 km, and went 30 km by bus
check:
time walking = 5/5 = 1 hr
time on bus = 30/60 = 1/2 hr
total is 1.5 hrsposted by Reiny
