\[\begin{aligned} 13\,380\text{ м} &= \boxed{\smash[b]{\underset{\hspace{4em}}{\textcolor{#e03131}{\mathbf{13}}}}}\text{ км }\boxed{\smash[b]{\underset{\hspace{4em}}{\textcolor{#e03131}{\mathbf{380}}}}}\text{ м} \\ 137\text{ с} &= \boxed{\smash[b]{\underset{\hspace{4em}}{\textcolor{#e03131}{\mathbf{2}}}}}\text{ мин }\boxed{\smash[b]{\underset{\hspace{4em}}{\textcolor{#e03131}{\mathbf{17}}}}}\text{ с} \\ 6\,090\text{ кг} &= \boxed{\smash[b]{\underset{\hspace{4em}}{\textcolor{#e03131}{\mathbf{6}}}}}\text{ т }\boxed{\smash[b]{\underset{\hspace{4em}}{\textcolor{#e03131}{\mathbf{90}}}}}\text{ кг} \end{aligned}\]
\(1)\ 62 \cdot 5 = \textcolor{#e03131}{\mathbf{310}}\text{ (км)}\)
\(2)\ 650 - 310 = \textcolor{#e03131}{\mathbf{340}}\text{ (км)}\)
\(3)\ 340 : 5 = \textcolor{#e03131}{\mathbf{68}}\text{ (км/ч)}\)
Ответ: \(\textcolor{#e03131}{\mathbf{68}}\) км/ч.
\[\textcolor{#e03131}{\mathbf{250}}\textcolor{#e03131}{\mathbf{,}}\ \textcolor{#e03131}{\mathbf{500}}\textcolor{#e03131}{\mathbf{,}}\ \textcolor{#e03131}{\mathbf{750}}\]
