Question

the typical american man has leg length of 0.85 m and walks at speed 0f 1.4 m/s. giraffe'$ legs are 1.8 m long: at what speed do you expect

Answer 1

Assuming a similar stride length in proportion to leg length, a giraffe, with legs of 1.8 meters, might walk at an expected speed of around 3 meters per second.

Step-by-step explanation:

To estimate the giraffe's walking speed based on its longer legs compared to a typical American man:

Stride Length Ratio: Since a giraffe has longer legs (1.8 m) compared to the typical American man (0.85 m), assume that the stride length of a giraffe is directly proportional to its leg length.

Ratio = Giraffe's leg length / American man's leg length

Ratio = 1.8 m / 0.85 m ≈ 2.12

Speed Ratio: Assuming a similar walking style and pace efficiency, the speed is proportional to the stride length.

Expected giraffe's speed = Speed of American man * Stride Length Ratio

Expected giraffe's speed = 1.4 m/s * 2.12 ≈ 2.97 m/s ≈ 3 m/s (rounded)

Therefore, based on the proportionality between leg length and walking speed, we can estimate that a giraffe, with legs of 1.8 meters, might walk at an expected speed of around 3 meters per second.

Answer 2

The expected speed of a giraffe with legs measuring 1.8 meters, based on the given information about the typical American man's leg length and walking speed, is approximately 1.29 m/s.

Step-by-step explanation:

The length of an object's legs is not directly related to their speed. The speed of an object depends on its velocity, which is the rate at which it changes its position. To calculate the expected speed of the giraffe, we need to use the formula:

Speed = Distance / Time

Since the length of the giraffe's legs is given as 1.8 m, we can use this value for the distance. We know that the typical American man walks at a speed of 1.4 m/s, so we can use this value for the time.

Plugging these values into the formula:

Speed = 1.8 m / 1.4 s = 1.2857 m/s

Therefore, we can expect the giraffe to walk at a speed of approximately 1.29 m/s.
