You and your friend enjoy riding your bicycles. Today is a beautiful sunny day, so the two of you are taking a long ride out in the country side. Leaving your home in Sunshine, you ride 6 miles due west to the town of Happyville, where you turn south and ride 8 miles to the town of Crimson. When the sun begins to go down, you decide that it is time to start for home. There is a road that goes directly from Crimson back to Sunshine. If you want to take the shortest route home, do you take this new road, or do you go back the way you came? Justify your decision. How much further would the longer route be than the shorter route? Assume all roads are straight.

Mathematics

$a = \frac{vf - vi}{t}$

$1.5 = \frac{7.5 - vi}{5.0}$

$1.5(5.0) = \frac{7.5 - vi}{5.0} (5.0)$

7.5 = 7.5 - vi

7.5 - 7.5 = 7.5 - 7.5 - vi

0 = vi

The car's initial speed is 0 m/s

$a = \frac{7.5 - 0}{5}$

a = 1.5
