All our streets run northsouth or eastwest, and the shop is 6 blocks east and 8 blocks north.I lost both races.The first tim, i rode directly east for 6 blocks and then directly north for 8 blocks.the next time i tried zigzagging.both times he was laughing when i got there can you tell how many blocks he beat me by? prove your answer by trying different equations

You have provided no information on the speed of the other bike rider except that he beat you.
Your total distance covered in the zigzag route is the same as in the eastandthennorth route.
More info is needed to answer your question. 
he rides the bike in the same speed
