3.75 block per minutes.

Step-by-step explanation:

Given: Thane take 48 minutes more to travel 36 blocks on foot than on his skates.

Thane´s average speed on skate is 6 times as his walking speed.

Lets assume time to walk a block is "x" minutes.

Time taken to skate a block is

Time to walk 36 blocks is 36x min.  

We know, Number of minutes it take to skate 36 block=

∴ We can say,

subtracting 6x and adding 48 on both side.

⇒

cross multiplying

∴ x=  

Time taken to walk a block is 1.60 minutes,

Next converting it into speed,

As checking multiples, we get Thane can walk 5 block in 8 mins

∴

Time taken to skate is 6 time faster than walking speed.

∴

Hence, Thane´s average speed on skates in blocks per minute is 3.75 block/ min.
