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. If k represents the number of kilometers and m represents the number of miles, who wrote the correct equation that would relate kilometers to mile? Explain why.
Oscar wrote the equation k = 1.6m, and he said the unit 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
Oscar is correct

Lin and Andre biked home from school at a steady pace. Lin biked 1.5 km and it took her 5 minutes. Andre biked 2 km and it took him 8 minutes.
-Draw a graph with two lines that represent the bike rides of Lin and Andre. (Make sure you correctly label the graph with axes, title, and an appropriate scale!)
-For each line, highlight the point with coordinates (1, r). What does this coordinate point mean in context of the problem?
-Who was biking faster? Explain how you know.
