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?

Jeff’s pace is 5 miles ÷ 2 hours = 2.5 miles per hour, so the distance after t hours is d = 2.5t. The relationship is continuous because time and distance can include fractional values while he is hiking. Therefore, the correct choice is d = 2.5t, continuous.
