Final answer:
The bookworm travels approximately 32.02 cm.
Step-by-step explanation:
The distance traveled by the bookworm can be calculated using the Pythagorean theorem. Let's assume that the inside back cover of Volume I is point A and the front cover of Volume II is point B.
We can consider the distance traveled by the bookworm as the hypotenuse of a right triangle, with leg AB being the length of Volume I and leg BC being the length of Volume II.
Since the bookworm travels in a straight line from A to B, we can use the Pythagorean theorem:
AB^2 + BC^2 = AC^2.
Let's assign values to AB and BC. If AB = 25 cm and BC = 20 cm, we can substitute these values into the equation:
(25 cm)^2 + (20 cm)^2 = AC^2.
Simplifying the equation, we get 625 cm^2 + 400 cm^2 = AC^2.
Combining like terms, we have 1025 cm^2 = AC^2.
To find the value of AC, we take the square root of both sides:
AC ≈ √1025 cm ≈ 32.02 cm.
Therefore, the bookworm travels approximately 32.02 cm.
