For this case we have the following system of equations: [tex]5x + 60y = 35
x + y = 1.5[/tex] Where, x: time in hours walking Y: time in hours on the bus We solve the system of equations. Rewriting the system we have: [tex]5x + 60y = 35
-60x -60y = -90[/tex] Adding both equations we have: [tex]-55x = -55
[/tex] Clearing x we have: [tex]x = -55 / -55
x = 1[/tex] Then, the number of Yochanan road miles is: [tex]5x = 5 (1) = 5
[/tex] Answer: Yochanan walked about: 5 miles
