Question

Lucy takes 20 minutes to cover a mile on foot. Identify the graph that shows the relationship between time taken and distance covered and the parent function that best describes it. Then use the graph to estimate the time it would take Lucy to cover 3.5 miles.
quadratic; 30 minutes
linear; 140 minutes
linear; 70 minutes

Answer 1

Answer:

  linear; 70 minutes

Step-by-step explanation:

No graphs are attached to your question here, so we cannot identify the graph for you. It will be one with time on the vertical axis and distance on the horizontal axis. The time scale will show it takes Lucy 20 more minutes for each additional mile she walks. The shape of the graph will be a straight line through the origin.

  (20 min/mi) × (3.5 mi) = (20×3.5) min = 70 min

It will take Lucy 70 minutes to cover 3.5 miles at her 20 min/mile pace.
