Answer 1

Answer:

57.5 miles is 92 km

Step-by-step explanation:

Miles                   km

  5                        8

 57.5                    x

                                    $\frac{5}{57.5} = \frac{8}{x}$                         $[ \ cross \ multiply \ ]$

                                    $5 \times x = 8 \times 57.5\\\\5 \times x = 460\\\\x = \frac{460}{5} =92 \ km$
