Question 1091608
Luis Nunez begins walking at a rate of 8 mph. 
Forty-five minutes after he​ leaves, his​ wife, Kristin, realizes that Luis has forgotten his wallet. Kristin gets on her bicycle and begins riding at a rate of 
28 mph along the same path that Luis took.

a)how long will it take Kristin to catch luis?
b)how far from their house will Kristin catch luis?
<pre>Let time Kristin takes to get to catch-up point, be T
Then time Luis takes to get to catch-up point = {{{matrix(1,5, T + 45/60, ",", or, T + 3/4, hours)}}}
We then get the following DISTANCE equation: {{{matrix(1,3, 28T, "=", 8(T + 3/4))}}}
28T = 8T + 6
28T - 8T = 6
20T = 6
T, or time Kristin takes = {{{highlight_green(matrix(1,5, 6/20, "hour,", or, 18, minutes))}}}
Distance traveled from house to catch-up point: {{{highlight_green(matrix(1,6, 28(6/20), "=", 42/5, "=", 8.4, miles))}}}
<b><u>IGNORE that person who claims the time to be about 13 minutes. Most times he/she does NOT HAVE a clue.</b></u>
Everyday, I wonder what they're doing on here, because they're not helping, but compounding people's math anxiety by giving them WRONG answers, most times. 
He/she is yet to realize that most times, his/her answers just DO NOT <b><u>ADD UP.</b></u> I wonder if he/she will EVER realize that.
