Superman needs to save Lois from the clutches of Lex Luthor. After flying for 6 seconds, he is 2430 meters
from her. Then at 9 seconds he is 2295 meters from her.
What is Superman's average speed?
meters per second m/s
How far from Lois did Superman start?
meters
Write an equation to model this situation (use d for distance from Lois in meters and s for seconds).
Two cars are traveling down the road. Car a travels for 10 seconds at 25 m/s and car b accelerates uniformly from 20 to 28 m/s over 10 seconds. Which car travels the furthest during this 10 second time interval?
