Question

PLEASE HELP MEDALS GIVEN A car's speed increases as it merges onto a highway. The car travels at 65 mi/h on the highway until it slows to exit. The car then stops at three traffic lights until it reaches its destination. Draw a sketch of a graph that shows the car's speed over time. Label each section.

Answer 1

Decide how long each traffic light is, then put speed = 0 for those three sections.
Have it speed up and slow down before each light and then stop at its destination.
