Answer:

45 miles/hour

Step-by-step explanation:

We need the speed in miles per hour so we need to changes minutes to hours

20 minutes * 1 hour /60 minutes = 1/3 hour

Speed = distance/ time

           = 15 miles/(1/3 hour)

            =15 *3 miles/hour

            = 45 miles /hour

Solve the following quadratic equations by completing the square.<br><br> y^2-14y+48=0
NISA [10]

Answer:

  y = 6 or 8

Step-by-step explanation:

1. Subtract the constant:

  y^2 -14y = -48

2. Add the square of half the y-coefficient:

  y^2 -14y +49 = -48 +49

Write as a square, if you like:

  (y -7)^2 = 1

3. Take the square root:

  y -7 = ±√1 = ±1

4. Add the opposite of the constant on the left:

  y = 7 ±1  =  6 or 8

The solution is y = 6 or y = 8.
