Answer:
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Step-by-step explanation:
Let x = Courtney's walking speed
then
(x + 1) = Brandi's walking speed
:
Time = Distance/speed
Brandi walks 6.5 mi time = Courtney walks 5 mi time
6.5/x + 1 = 5/x
Cross multiply
6.5x= 5(x+1)
6.5x= 5x + 5
6.5x - 5x = 5
1.5x = 5
x = 5/1.5
x = 3.33 mph is Courtney's walking speed
Note that:
(x + 1) = Brandi's walking speed
3.33mph + 1 = 4.33mph
Therefore,
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
The rectangle has the dimensions 4 x 3.
The measure of 6 ft is the triangle plus the square's length.
The rectangle's length is 3.
To find the triangle's width, solve this: 3 + x = 6
Subtract 3 from each side to get x = 3.
The dimensions of the triangle is 3 x 4.
The area will be half of 3 x 4, so 12 / 2 or 6.
The rectangle's area is 12 because its dimensions are 3 x 4.
12 + 6 = 18 feet total.
Hope this helps!
