Let
v = the average waking speed in blocks per minute
6v = the average skating speed in blocks per minute
Since average speed = distance/time follows time = distance/average speed:
36/v = 48 + 36/6v

v = 0.625 blocks per min
6*0.625 = 3.75 blocks per min
Tahane's average speed on skates is 3.75 blocks per minute.
