Lizette ran for 1.25 hours and walked for 3 hours.

  distance = speed × time

Her total distance is the sum of her distances at the different speeds. Let w represent her walking speed in mi/h. For distances in miles, speeds in miles per hour, and time in hours, the problem statement tells us ...

  19 = (w+5)(1.25) + (w)(3)
  19 = 4.25w + 6.25 . . . . collect terms
  12.75 = 4.25w . . . . . . . subtract 6.25
  3 = w . . . . . . . . . . . . . . . divide by 4.25

Lizette's walking speed is 3 mph.
Lizette's running speed is 8 mph.

ExtremeBDS [4]

Answer:

A. 44.82%

B.

Option b. Return On Equity usually increases since the repurchase of shares reduces the denominator (avg. stockholders' equity)

C.

Option b. The Companies would tend to repurchase their own stock if they feel the stock is been undervalued by the market

Step-by-step explanation:

a. Computation for return on equity for 2015

Using this formula

Return on equity = The Net income amount /The Average stockholders' equity amount

Let plug in the formula

Return on equity=2,634.4/[(5,605+6,151)/2]

Return on equity=2,634.4/(11,756/2)

Return on equity=2,634.4/5,878

Return on equity=0.4482×100

Return on equity= 44.82%

b. In a situation where they repurchased over $1.4 billion of its common stock in the year 2015 this means that the RETURN ON EQUITY will usually tend to increases reason been that the repurchase of shares will often reduces the denominator (average stockholders' equity)

Therefore the repurchase increase Starbucks’ Return On Equity.

c. In a situation where Starbucks had not repurchased common stock in the year 2015, what their Return On Equity would have been is that they will repurchase their own stock if they feel the stock is been undervalued by the market
