How many hours does it take a car to travel 70 miles at an average speed of 35 miles per hour?
| 5 hours | |
| 2 hours | |
| 7 hours | |
| 9 hours |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for time:
time = \( \frac{\text{distance}}{\text{speed}} \)
time = \( \frac{70mi}{35mph} \)
2 hours
If the ratio of home fans to visiting fans in a crowd is 3:1 and all 40,000 seats in a stadium are filled, how many home fans are in attendance?
| 40,000 | |
| 30,000 | |
| 31,200 | |
| 26,000 |
A ratio of 3:1 means that there are 3 home fans for every one visiting fan. So, of every 4 fans, 3 are home fans and \( \frac{3}{4} \) of every fan in the stadium is a home fan:
40,000 fans x \( \frac{3}{4} \) = \( \frac{120000}{4} \) = 30,000 fans.

If there were a total of 150 raffle tickets sold and you bought 9 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 9% | |
| 14% | |
| 7% |
You have 9 out of the total of 150 raffle tickets sold so you have a (\( \frac{9}{150} \)) x 100 = \( \frac{9 \times 100}{150} \) = \( \frac{900}{150} \) = 6% chance to win the raffle.
