It is not reasonable, because we know by estimating that 29.4 × 8.6 is approximately (but less than) 30 * 9 = 270, which is way less than 2528.4.
The <span>graph most accurately represents this scenario is the graph that started at (0,0) and goes up diagonally upward to a point ( 0.5 hr, y1). then goes horizontally straight for 2 hours because it does not travel just shopping (2.5, y1). then another diagonally upward to (2.75, y2). then another horizontal for 1 hr. (3.75, y2)</span>
(10 - 5 2/3)(-2) + x = 8 + 2/3
(4 1/3)(-2) + x = 8 2/3
-8 2/3 + x = 8 2/3
x = 8 2/3 + 8 2/3 = 17 1/3
