To ride to school, Elaine takes minutes to ride blocks. What is her unit rate (blocks per minute)? Assuming she rides at a constant speed, how long should it take her to go blocks? Justify your answer.

Set up a fraction to find the unit rate.

Now find how long it should take her to go block, then find how long it should take to go blocks.
