Question

Two skaters are racing toward the finish line of a race. The first skater has a 40 meters lead and is traveling at a rate of 12 meters per second. The second skater traveling at a rate of 14 meters per second. How long will it take for the second skater to pass the first skater?

Answer 1

So the first skaters equation is y = 12x + 40 (red) and the second skaters equation is y = 14x and after my math i got 14x = 12x + 40
14x - 12x = 40
2x = 40
x = 40/2
x = 20 seconds for skater 2 to pass skater 1
So 20 seconds
