A tortoise and a hare are competing in a 1200-meter race. The arrogant hare decides to let the tortoise have a 555-meter head start. When the start gun is fired the hare begins running at a constant speed of 14 meters per second and the tortoise begins crawling at a constant speed of 6 meters per second. Let t represent the number of seconds that have elapsed since the start gun was fired. a. Write an expression in terms of t that represents the hare's distance from the starting line (in meters). (555-6t) Preview (555 – 6t) syntax ok b. Write an expression in terms of t that represents the tortoise's distance from the starting line (in meters). Preview c. Write an equation for the number of meters, D, the tortoise is ahead of the hare in terms of t. Preview d. How many seconds does it take the hare to finish the finish the race? Preview e. How many seconds does it take the tortoise to finish the finish the race? Preview f. Who finishes the race first? Select an answer

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
