+36916 Rate * Time = Distance
w = walking rate
b = biking rate = w +8
(w+8) * 25/60 = distance (25/60 is the amount of hours 25 min = 25/60 hours)
w * 1.25 = distance
(w+8) * 25/60 = w * 1.25
25/60 w + 8 * 25/60 = 1.25 w
3 1/3 = 1.25 w - 25/60 w
= .8333w
w = 3 1/3 / .8333 = 4 km /hr = walking speed
rate x time = distance
4 km/hr * 1.25 hr = 5 km = distance between house and repair shop
