Question

A curved bridge is shown below. If a straight line is drawn from the starting point P of the bridge to the ending point Q, the length of this line is 3 m.

A man starts from point P and walks along the bridge to point Q. How much distance has he travelled?

Answer 1

Without additional information about the curved bridge, such as its arc length, it is not possible to determine the exact distance the man travelled from P to Q.

Step-by-step explanation:

The question pertains to finding the distance a man has travelled along a curved bridge from point P to point Q. The given straight line length from P to Q is 3 meters, but as this is a curved bridge, the actual distance travelled by the man along the bridge would be longer than the straight-line distance. To calculate the man's distance, we would need to know the specific properties of the curve, such as its arc length, which isn't provided in the question. As such, with the information given, the question cannot be answered definitively.

Answer 2

Answer: To determine the distance the man has traveled along the curved bridge from point P to point Q, we need to consider the length of the curved path.

Since the problem states that the length of the straight line connecting P and Q is 3 meters, it implies that the straight line is the chord of the curve. However, we need more information about the bridge's shape to accurately calculate the distance traveled along the curve.

If you provide additional details about the shape of the curved bridge (e.g., radius of curvature, information about the arc, etc.), I can assist you in calculating the distance traveled.
