Charmaine runs 6miles in 45 minutes at the same rate how many minutes would she take to run 4 miles
2 answers:
It takes 30.07 minutes for Charmaine to run 4 miles
Step-by-step explanation:
Given:
Distance covered by Charmaine = 6 miles
Time taken by Charmaine to run 6 miles = 45 minutes
To find:
Time taken by Charmaine to run 4 miles=?
Solution:
We know that ,
...................(1)
Substituting the values given in the question,
speed=0.133 miles/minute
Re writing the equation (1), we have,
Now substituting the spees and distance values, we get
Time taken by Charmaine to run 4 miles=
Time taken by Charmaine to run 4 miles= 30.07 minutes.

Both A and C would be solutions to the equation.
In order to solve for this you must first get the equation equal to 0.
2x^2+5x+8=6 ----> subtract 6 from both sides
2x^2 + 5x + 2 = 0
Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.
a = 2 (because it is the coefficient to x^2)
b = 5 (because it is the coefficient to x)
c = 2 (because it is the end number)
Now we can plug these values into the quadratic equation.
or -1/2 for the first answer
or -2 for the second answer
