\begin{document}
When hydrogen is the fuel used:
\begin{equation*}
U_t=2249\ln \frac{1\times10^{6}{1\times10^6-424.6t}}
\end{equation*}
When kerosene is the fuel used:
\begin{equation*}
U_t=1737\ln \frac{1\times10^{6}{1\times10^6-1022t}}
\end{equation*}

答案1
如上所述,“分数”有问题。使用命令创建分数\frac{numerator}{denominator}
。请参阅这里以获得一些很好的提示。
否则,请尝试:
When hydrogen is the fuel used:
\begin{equation*}
U_t=2249\ln\frac{1\times10^6}{1\times10^{6-424t}}
\end{equation*}
