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 π‘˜ represents the number of kilometers and π‘š represents the number of miles, who wrote the correct equation that would relate miles to kilometers? EXPLAIN WHY?? Oscar wrote the equation π‘˜=1.6π‘š, and he said that the rate 1.6/1 represents kilometers per mile. Maria wrote the equation π‘˜=0.625π‘š as her equation, and she said that 0.625 represents kilometers per mile.

It is confusing isn't it.  

Let's see.

   k  :   m

 152:  95

 

152k=95m

divide both by 95

and you get

1.6kilometres=1m  

1.6 kilometre/mile     so oscar is right.

BUT

152k=95m

if you divide by 152 you get

1k=95/152 m

1k=0.625miles      so 

0.625 miles/kilometre  so  Maria has it the wrong way around.
