There are 2 friends chasing one another. They are 80 feet apart. Caroline is chasing after.Sam runs at a speed of 22 feet per second and caroline runs at a speed of 31 feet per second .How many seconds will it take for caroline to catch Sam?
<pre>
Caroline's approach rate to Sam is 31-22 or 9 feet per second. Since
t = {{{d/r}}}, t = {{{80/9}}} = {{{8&8/9}}} seconds.
