Time(s) 1 2 3 4

Sally's Distance(m) 2 4 6 8

Alonzo's Distance(m) 1 2 2 4

Make a distance-time graph that shows the motion of both runners. What is the average speed of each runner? Which runner stops briefly? Over what time interval do they both have the same speed?

**drwls**, Thursday, November 3, 2011 at 7:35pmWe don't provide ghaphs. Surely you can plot those points yourself.

The average speed of Sally is 8 m/4 s = 2 m/s. That of Alonzo is half as much.

Alonzo does not move between t=2 and t=3 s

They have the same speed where the slopes of the two curves are equal. They both move 2 m in the last second.
