Answer:

The answer to your question is speed = 9 m/s

Step-by-step explanation:

Data

Winner Last runner

time = 45 s time = 48 s

speed = 9.6 m/s

Process

1) Calculate the distance they ran using the data of the winner

speed = distance / time

-Solve for distance

distance = speed x time

-Substitution

distance = (9.6)(45)

-Result

distance = 432 m

2.- Calculate the speed of the last runner

-Substitution

speed = 432/48

-Result

speed = 9 m/s
