Mike has two toy boats. The first travels at a constant rate of ft/sec. The second accelerates so that it has a rate of ft/sec.

  1. Sketch speed vs. time graphs for each boat.

    Put time on the -axis and speed (or rate) on the -axis.

  2. How far has each boat traveled after seconds?

    Distance = (rate)(time), or using your graph
    it is the area under the curve.

  3. How far will they have traveled after seconds?

    First boat:
    Second boat:

  4. When will the second boat pass the first?

    When .
