Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:
60x7=420 Then you add 30 seconds equaling 450 seconds total
Then you divide 450 by 4 since she ran 4 laps.
So, Stephanie ran 112.5 seconds per lap
Since 150 is the total and 12 is per week you can actuality do this equation
T= Total,150$ W=Amount saved,12$
150=12*X or 150/12=X
While X = 12.5 Weeks So, the correct answer
is 12.5 Weeks it can be stated As,
12 weeks 3 days 12 hours (X=12.5)
.67%
hope this helps.

Answer: D
Step-by-step explanation:
so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.
So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.
1/4 * 2/1= 2/4 = 1/2
