Answer:
"You" rode 32km and "your friend" rode 40km.
Explanation:
Okay so this is a relay race which means that "you" and "your friend" combined road 72km. It was divided into 9 equal sections according to the tape diagram.
72/9 = 8 which means that each section of the tape diagram = 8.
"You" have four sections and each of them equal 8 which means 4x8= 32.
"Your friend" has five sections which means 5x8= 40.

So, "you" rode 32km and "your friend" rode 40km.
36/12 = 3
so multiply everything by 3
