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.

Answer:
A = 89 m^2
Step-by-step explanation:
First, find the area of the rectangle
A = L x W
A = 13 x 8
A = 104 m^2
Next, find the area of the triangle
A = 1/2BH
A = 1/2 (5)(6)
A = 1/2(30)
A = 15 m^2
Now subtract the area of the triangle from the area of the rectangle.
104 - 15 = 89 m^2
