                SPEED            TIME           DISTANCE

BIKE            14               8-x             14(8-x)

WALK             2               x                2x

TOTALS                           8                52

14%288-x%29%2B2x=52
-
112-14x%2B2x=52
-12x%2B112=52
112-52=12x
12x=60
x=5
Bike for 3 hours, walk for 5 hours
