Calculate Time in Minutes:  Calculate the actual time taken and the expected time in minutes for better precision in calculations. Expected time: 3 hours 30 minutes = 210 minutes. Actual time: 4 hours = 240 minutes. Find Time Difference:  Find the difference in time between the actual and expected durations. Difference = 240 minutes - 210 minutes = 30 minutes. Calculate Percent Error:  Calculate the percent error using the formula: Percent Error = (|Actual - Expected| / Expected) × 100. Percent Error = (30 / 210) × 100. Perform Division and Multiplication:  Perform the division and multiplication to find the percent error. Percent Error = 0.142857 × 100 = 14.2857%. Round Percent Error:  Round the percent error to the nearest tenth. Rounded Percent Error = 14.3%.
