Explanation:

Step1: Identify total number of trains

The total number of trains in the week is 210 (from the bottom - right cell of the table).

Step2: Identify number of late trains

The total number of late trains in the week is 58 (from the 'Late' row and 'Total' column).

Step3: Calculate the percentage of late trains

The formula for percentage is $\text{Percentage}=\frac{\text{Number of late trains}}{\text{Total number of trains}}\times100$. Substitute the values: $\frac{58}{210}\times100=\frac{5800}{210}\approx27.6\%$.

Answer:

27.6%
