Damon loaned Ezra $500 at an annual interest rate of 2%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $66 | |
| $15 | |
| $10 | |
| $55 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $500
i = 0.02 x $500
i = $10
What is the distance in miles of a trip that takes 5 hours at an average speed of 15 miles per hour?
| 270 miles | |
| 105 miles | |
| 30 miles | |
| 75 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 = \( 15mph \times 5h \)
75 miles
