Yochanan walked from home to the bus stop at an average speed of 5 mph. He immediately got on
his school bus and traveled at an average speed of 60 mph until he got to school. The total distance
from his home to school is 35 miles, and the entire trip took 1.5 hours. The following system of
equations represents this:
5x + 60y = 35
x + y = 1.5
