Jeff hiked for 2 hours and traveled 5 miles. If he continues at the same pace, which equation will show the relationship between the time, t, in hours he hikes to distance, d, in miles? Will the graph be continuous or discrete?

d = 0.4t, discrete
d = 0.4t, continuous
d = 2.5t, discrete
d = 2.5t, continuous

You need to find the unit rate (the rate of miles he does in one hour)

To do this you need to divide your known miles by your known number of hours.

$\bf\large{\frac{5}{2} = ?}$

The decimal you get is your number of miles in one hour, which is set up as:

$\bf\large{d = ?t}$
