Oscar and Maria each wrote an equation that they felt represented the proportional relationship between distance in kilometers and distance in miles. One entry in the table paired 152 km with 95 miles.

-Oscar wrote the equation k=1.6m and he said that the rate 1.6/1 represents kilometers per mile. -Maria wrote the equation k=0.625m as her equation, and she said that 0.625 represents kilometers per mile. If k represents the number of kilometers and m represents the number of miles, who wrote the correct equation that would relate kilometers to miles? why?
