Question 1006521
Melissa and kyle went on strip to visit relatives.On the way there.M drove and average about 34 mph, on the way home, k drove about 50 mph. Total drive time was 21 hours, how long did M drive, how long did K drive?
<pre>Let time Melissa drove be T
Then time Kyle drove = 21 – T
We then get: 34T = 50(21 – T)
34T = 1,050 – 50T
34T + 50T = 1,050 
84T = 1,050
T, or time Melissa drove = {{{1050/84}}}, or {{{highlight_green(12.5)}}} hours
Therefore, Kyle drove: 21 – 12.5, or {{{highlight_green(8.5)}}} hours
