If total distance is  3d,

             SPEED         TIME         DISTANCE

Biking        2d/x            x             2d

Walking       d/(3x)         3x             d

how many times faster is his biking speed than his walking speed?

6 times as fast is 5 times faster.
================
Is 1 time faster, a 100% increase in speed, the same speed?
Or 2x as fast?
