Here is an easy way to remember, If the discriminant is equal to zero there will be one solution, if the discriminant is less than 0 or negative there are no real solutions, more than 0 or positive there will be two. So one real solution if it is equal

The fastest runs 2,464 feet in 22.4 seconds. How many miles per hour is that?

Juliette [100K]

Thirty miles per hour. First you divide 2,464 feet by 22.4. you should get 110 feet which is per second, then you multiply it by 60 representing one minute but in seconds, you should get 6,600 feet per minute, then you multiply it by 60 mins and you should get 396,000 feet per minute. Next, you multiply 396,000 by 24 hours, the result is 9,504,000 feet per hour. Finally, you divide 9,504,000 by 5280 (there is 5280 feet in one mile) and the answer is 30 miles per hour.
