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

Step-by-step explanation:
Probability is found by dividing the number of favorable outcomes by the total number of outcomes.

For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.
The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).

This fraction cannot be reduced, so the probability of selecting a blue or green marble is <u>8/13.</u>
There isn't an obvious question to this problem but with the given we can assume what is to be asked. I think we are to find the total cost of a certain poultry seasoning. The poultry seasoning would have a total weight of 4+2=6 ounces. The total cost will then have to be 4(4) + 2(3) = 22 dollars.
The scale factor from the small one to the big one is 3
