CPM Homework Help : CC2 Problem 6-114

Walter walked $15.5$ blocks from his house to work. It took him $35$ minutes. What is his rate in blocks per hour?

Step 1:

Since you want the answer in blocks per hour, you must first convert $35$ minutes to hours.

$\frac{35}{60}=\frac{7}{12}\text{hours}$

Step 2:

Now divide $15.5$ by the new time.

$\frac{15\frac{1}{2}}{\frac{7}{2}}=26\frac{4}{7}\frac{\text{blocks}}{\text{hour}}$

Answer:

$26\frac{4}{7}\frac{\text{blocks}}{\text{hour}}$
