Question

Identify the independent and dependent quantities and their units.David rode his bike to the park. After staying at the park for a while, he continued his ride to thegrocery store. The graph shown represents this situation.

Answer 1

when the time is between 0 and 15 minutes, the distance depends on the time on a relation: d =(1/10)t

when the time is between 15 and 40 minutes, the distance is independent of the time, it is fixed d = 1.5 miles

when the time is between 40 and 50 minutes, the distance depends on the time on the relation: d = 1.5 + (1/10)(t - 40)
