If a car travels 520 miles in 8 hours, what is the average speed?
| 65 mph | |
| 60 mph | |
| 25 mph | |
| 35 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)What is the distance in miles of a trip that takes 5 hours at an average speed of 20 miles per hour?
| 585 miles | |
| 100 miles | |
| 540 miles | |
| 385 miles |
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 distance:
distance = \( \text{speed} \times \text{time} \)
distance = \( 20mph \times 5h \)
100 miles

Christine scored 95% on the test meaning she earned 95% of the possible points on the test. There were 160 possible points on the test so she earned 160 x 0.95 = 152 points. Each question is worth 4 points so she got \( \frac{152}{4} \) = 38 questions right.
4! = ?
4 x 3 |
|
4 x 3 x 2 x 1 |
|
3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
