Q
Q: A speed is recorded as 60 km/h with an error of 2 km/h. What is the percentage error?
Solution:
Percentage error = (Absolute error / Measured value) * 100 = (2 / 60) * 100 = 3.33%
Steps: 7
Show Steps
Step 1: Identify the measured value, which is 60 km/h.
Step 2: Identify the absolute error, which is 2 km/h.
Step 3: Use the formula for percentage error: Percentage error = (Absolute error / Measured value) * 100.
Step 4: Substitute the values into the formula: Percentage error = (2 / 60) * 100.
Step 5: Calculate the division: 2 divided by 60 equals 0.0333.
Step 6: Multiply the result by 100 to find the percentage: 0.0333 * 100 equals 3.33.
Step 7: Conclude that the percentage error is 3.33%.
