Sam ran 63;756 feet in 70 minutes. What is Sam's rate in miles per hour? (There are 5,280 feet in one mile.) Step 1: What is Sam's rate as stated? \( \frac{63,756 \text { feet } ~}{5,280 \text { feet } ~} \)

\( \frac { 1 } { 2 } + \frac { 2 } { 3 } + \frac { 3 } { 4 } + \frac { 4 } { 5 } + \frac { 5 } { 6 } + \ldots + \frac { 20 } { 21 } \)
