Answer 1

We have in this case
 5x + 60y = 35
 x + y = 1.5
 For this case what we must do is solve the system of equations.
 Applying the graphic solution we have:
 x = 1 h
 y = 0.5 h
 Note: see attached image for the solution.
 Therefore, Yochanan walked:
 (1) * (5) = 5 miles
 Answer:
 Yochanan walked about:
 5 miles

Answer 2

X + y = 1.5
x = 1.5 - y

Bring that into 5x + 60y = 35
5 (1.5 - y) + 60y = 35
7.5 - 5y + 60y = 35
62.5y = 35
y = 0.56

Bring that into x + y = 1.5
x + 0.56 = 1.5
x = 1.5-0.56
x = 0.94

Hope this helps.
