Final answer:
Using the Pythagorean theorem, the straight-line distance from Kelvin's home to the ballpark is found to be approximately 11.2 blocks, illustrating a practical scenario of a two-dimensional path.
Step-by-step explanation:
The task is to find the straight-line distance from Kelvin's home to the ballpark. If Kelvin walks 5 blocks east and 10 blocks north, the scenario can be visualized as a right-angled triangle where the two paths (east and north) represent the perpendicular sides of the triangle. The straight-line path would then be the hypotenuse of this triangle. Applying the Pythagorean theorem (a2 + b2 = c2), we calculate the hypotenuse:
- For the eastward path, a = 5 blocks
- For the northward path, b = 10 blocks
- Calculate c2 = (5)2 + (10)2
- c2 = 25 + 100
- c2 = 125
- Take the square root of both sides to find c
- c ≈ √125 ≈ 11.2 blocks
Therefore, the ballpark is approximately 11.2 blocks away from Kelvin's home on a direct path.
