1. Pick two animals to be in a race and answer the following questions.
   

ASuppose two animals are in a race. Choose the two animals and calculate the speed of each animal in yards per second.

BDecide how much of a head start (in yards) the faster animal offers the slower animal. For each animal, write an equation relating distance from the starting line to time.

CGraph the two equations on the same coordinate plane.

DHow long will it take the faster animal to overtake the slower animal? How

many yards from the starting line are the animals when the faster animal

overtakes the slower animal?

EReduce the head start by half and repeat parts (c) and (d).

1. Pick a third animal and answer the following questions.
   
   

AChoose a third animal. Calculate its speed in yards per second. Compare its speed with the speed of the two animals you chose in Activity 1.

BDecide which two animals should get head starts and how much of a head start each should get. Write three equations relating distance from the starting line to time.

CGraph all three equations on the same coordinate plane.
