4 is the X variable so it means it is 4 weeks after the kitten is born. 14 is the Y variable so it means it is 14 ounces after 4 (this is the X variable) weeks.
You can use the distance equation.. d = rt d = distance = 645 r = rate = 215 mph t = time = ???? find the time 645 = 215t 645/215 = 215t / 215 3 = t t = 3 It took 3 hours
