  3. (a) For uniform motion, the time required for an object to travel equals the distance traveled divided by the velocity of the object. (b) The length of a rectangle is four times its width. (c) Five times a number, decreased by 3 (d) The product of 3 and a number increased by 5

  4. OBJECTIVE 2

  5. Suppose you borrow $1000 for 6 months at the simple interest rate of 6% per annum. What is the interest you will be charged on this loan? If you pay the loan back at the end of 6 months, what is the amount you must pay?
