Distance = Rate * Time

Note: Rate is the same as speed


So we have the formula d=rt


Since we're given that "A race car driver traveled 240 miles in 2 1/2", we know that d=240 and t=2%261%2F2 or t=5%2F2


So plug these values into the given formula to get 240=r%285%2F2%29. Then multiply both sides by 2 to get 480=5r and then divide both sides by 5 to get r=96


So the driver's speed is 96 mph. So the answer is C)
