Suppose that juan can run 200 yards
in 28 seconds. amy can run 88 yards
in 10 seconds. who is faster and by
how much per second?

For this case we find the number of yards for each second that runs each and compare:

Then, the difference is:

\frac {44} {5} -  \frac {50} {7} =  \frac {308} {35} -  \frac {250} {35}

\frac {44} {5} -  \frac {50} {7} = \frac {58} {35}

While Juan runs \frac {50} {7} yards per second, Amy runs  \frac {44} {5} yards per second. Amy is faster, runs \frac {58} {35} yards per second faster than Juan.

Amy is faster, runs \frac {58} {35} yards per second more than Juan.

200/28 = 7.1

Juan can run roughly 7.1 yards per second.

88/10 = 8.8

Amy can run roughly 8.8 yards per second.

8.8 - 7.1 = 1.7

Amy is faster by 1.7 yards per second.

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint
