Question

how long is the panama canal? select the best estimate. 50 miles 50 inches 50 yards 50 feet

Explanation:

Step1: Analyze the units

Inches, yards, and feet are relatively small units of length, suitable for measuring short distances (like the length of a room, a small object, etc.). Miles are a much larger unit, suitable for measuring long distances (like the length of a canal, a road between cities, etc.).

Step2: Evaluate the options

• 50 inches is very short (about 4 feet), too small for a canal.
• 50 yards is about 150 feet, still too short.
• 50 feet is also short, not suitable for a major canal like the Panama Canal.
• 50 miles is a reasonable length for a large canal that connects two oceans.

Answer:

50 miles
