Question

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

Answer 1

x and y are the times in hours that he travelled  on foot and on bus

x + y = 1.5   * by 5:-

5x + 5y  = 7.5
5x + 60y = 35    subtract:-

55y =  27.5
y = 0.5 
and x = 1.5 - 0.5 = 1

so he walked for 1 hour

distance he walked =  average speed * time =  5*1 = 5 miles.
