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?

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

Answer 1

Rate = 5 miles / 2 hours = 2.5 mi/h, so d = 2.5t. The graph is continuous (distance changes continuously with time).
