Question

If \( s \) is a speed, in miles per hour, at which the energy used per meter during running is twice the energy used per meter during walking, then according to the graph above, \( s \) is between

• A. 2.5 and 3.0
• B. 3.0 and 3.5
• C. 3.5 and 4.0
• D. 4.0 and 4.5
• E. 4.5 and 5.0

Hint:

Carefully interpret the graph to determine the speed range at which the desired energy relationship holds.

Answer 1

The Correct Option is B

This problem involves determining the speed at which the energy used per meter during running is twice that used per meter during walking, based on the graph. The desired speed is between 3.0 and 3.5 miles per hour.
Final Answer: \[ \boxed{\text{The correct answer is (B) More than half of the titles distributed by M are also distributed by L.}} \]
