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.

                                  [tex]\frac{3}{26} = \frac{7}{x}[/tex]

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

                                 x = [tex]\frac{26 x 7}{3}[/tex]

                                 x = [tex]\frac{182}{3}[/tex]

                                 x = 60.7 km
