Option C: 133%. Thomas' walking time today was 133% more than his walking time yesterday.
Given that:
Yesterday's walking time was 15 minutes
Today's walking time = 5 minutes + Yesterday's walking time = 5 + 15 = 20 minutes.

[tex]\begin{aligned} \text{percent needed} &= \dfrac{\text{Time taken today} \times 100}{\text{time taken yesterday}}\%\\&= \dfrac{20 \times 100}{15}\%\\&= \dfrac{400}{3}\%\\&= 133.333...\%\\&\approx 133\%\\\end{aligned}[/tex]
