Questions & Step-by-Step Solutions

The length of a rod is measured as 50 cm with an error of 1 cm. What is the minimum possible length?
  • Step 1: Identify the measured length of the rod, which is 50 cm.
  • Step 2: Identify the error in the measurement, which is 1 cm.
  • Step 3: To find the minimum possible length, subtract the error from the measured length.
  • Step 4: Perform the calculation: 50 cm (measured length) - 1 cm (error) = 49 cm.
  • Step 5: Conclude that the minimum possible length of the rod is 49 cm.
