You can put this solution on YOUR website!
_____________speed_______time_______distance
WALK TO_______6__________d/(6)______d
RIDE FROM_____18_________d/18_______d
TOTAL_____________________1

You really want d%2F6, according to the question but you can solve for d, first.
The time expressions are based on RT=D, T=D%2FR.


Essential Equation: highlight_green%28d%2F6%2Bd%2F18=1%29
%283d%2Bd%29%2F18=1
4d=18
d=18%2F4=highlight_green%289%2F2%29, miles for d.

Time spent walking, hours walking to school. That is 45 minutes.
