The relationship between distance travelled, d, and time, t, can be represented by a linear relation. In 45 minutes, a bus travelled 60 km. In 100 minutes, the same bus travelled 120 km. An equation that represents this linear relation is Select one: O a. y - 45 = 12 1( x -60) y - 60 = -. 12 O b. IT ( x -45) O Y- 45 =- 12 IT(x-60) O d. . y - 60 = 12 IT(x -45)
