Answer:

5 1/2 km

Explanation:

Let k represent the number of kilometers Maya can kayak in 44 minutes. Then the proportion is ...

[tex]\dfrac{3\frac{3}{4}}{30}=\dfrac{k}{44}[/tex]

This is solved by multiplying by 44, so ...

[tex]k=\dfrac{44\cdot 3\frac{3}{4}}{30}=\dfrac{22}{15}\cdot\dfrac{15}{4}\\\\=\dfrac{11}{2}=5\frac{1}{2}[/tex]

Maya can kayak 5 1/2 km in 44 minutes at the same rate.
