Lina and Michael studied the data in the table. They each wrote an equation to represent the relationship between the number of miles and the numbers of hours ridden by each bicyclist. Data : Miles, m ; Hours, h | 27m = 3h ; 45m = 5h ; 18m = 2h and 54m = 6h

Lina's equation: m = 9/h

Michael's Equation: h = 1/9m

The teacher said both of their answers were correct.. why?
