Question

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?

Answer 1

His speed is (number of miles) / (hours)

The equation should be something like

d = (speed) t

Now to determine whether it’s continuous or discrete, try to consider whether the t and d values can only be discrete (separate) values or are they continuous (they can take any value within the interval)
