Question

End of day/Distance from home

Answer 1

Answer:

$\large \boxed{\text{B) 374 mi/day}}$  

Step-by-step explanation:

The average rate of change from one point to another is the slope of the straight line joining the two points.

$\text{slope} = \dfrac{ y_{2} - y_{1}}{ x_{2} - x_{1}}$

From Day 1 to Day 3, your points are (1, 383) and (3, 1132).  

$\text{Slope} = \dfrac{1132 - 383 }{3 - 1} = \dfrac{749 }{2} = \textbf{374 mi/day}\\\\\text{The average rate of change from Day 1 to Day 3 was \large \boxed{\textbf{374 mi/day}} }$

The graph below shows the rate of change from Day 1 to Day 3 as a black line. It appears from the graph that Adam and his dad kept the same rate of change for the whole trip.
