Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
40 metres covered in 6 seconds
Max speed attained after 6seconds
75 meters covered after 11 seconds
Average Speed for first 40 meters :
Speed = distance / time
Speed = 40m / 6s
Speed = 6.67m/s
To obtain the maximum speed :
Next (75 - 40) meters = 35 meters was covered in (11 - 6)seconds = 5 seconds
Speed at this point is maximum :
Hence, maximum speed = (35m / 5s) = 7m/s
Suppose, Manuel runs for an additional z seconds after reaching max speed :
Distance from starting line 6+z seconds after race started?
Distance after 6 seconds = 40 metres
Distance after z seconds = 7 * z
Total distance = (40 + 7z)
What is Manuel's distance from the starting line x seconds after the race started (provided x≥6x)?
Distance for first 6 seconds = 40 meters + distance covered after 6 seconds = (7 * (x-6))
40 + 7(x - 6)
Answer:
The height of the triangle is 3.2 cm.
Step-by-step explanation:
The area of the triangle = 
Base of the triangle = 10 cm
Height of the triangle = h cm
Area of the triangle = 
h = 3.2 cm
The height of the triangle is 3.2 cm.
The answer is: 1.25x + 1.75

Answer:
54 km
Step-by-step explanation:
The distance she covers would be equal to twice the perimeter of the park which is in the shape of a rectangle
perimeter of a rectangle = 2 x (length x width)
length = 4.5
width = 2 x 4.5 = 9
2 x (4.5 + 9) = 27km
In one walk, she covers a distance of 27km. In two walks, she covers a total distance of 27km x 2 = 54km
