Time to walk a block is x minutes, and it takes (1/6)x minutes to skate it.
Time to walk 36 blocks is 36x
36x-48=number of minutes it takes him to skate it=6x minutes, since 1/6 of 36 x
30x=48
x=48/30=1.60 minutes to walk a block or 8 minutes to walk 5 blocks. That is 0.625 block/minute
That would make him able to skate 6 times faster or 3.75 blocks per minute. ANSWER
check
36 blocks at 3.75 per minute is 9.6 minutes to do it
36 blocks at 0.625 per minute is 57.6 minutes, or 48 minutes longer.
