Answer:

The answer to your question is 60.7 km

Step-by-step explanation:

This is a ratio and proportion problem, so let's write the proportion.

3 : 26 : : 7 : x

1.- Convert the expression to a fractional form.

$\frac{3}{26} = \frac{7}{x}$

2.- Solve the proportion, cross multiplying and back off.

x = $\frac{26 x 7}{3}$

x = $\frac{182}{3}$

x = 60.7 km
