Question

Imagine that you took a road trip. Based on the information in the table, what was the average speed of your car?
Time Mile marker
3:00 pm 11
8:00 pm 205

Answer 1

Speed is distance covered over time (even though this is velocity, it still applies, in this case):
\[
v=\frac{\Delta x}{\Delta t}=\frac{205-11}{8-3}=\frac{194}{5}
\]
And we are done.

Answer 2

Answer 3

and units?

Answer 4

Oh, well, we're dealing with how many miles recurred in a set of hours, so, mph.
