Answer:
- When t = 0, d = 0
- When t = 3, d = 6
- When t = 5, d = 10
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>PART ONE: Find d when t = 0</u>
<em>Given expression</em>
d = 2t
<em>Substitute value into the expression</em>
d = 2 (0)
<h2>d = 0</h2>
PART TWO: Find d when t = 3
<em>Given expression</em>
d = 2t
<em>Substitute value into the expression</em>
d = 2 (3)
<h2>d = 6</h2>
<u>PART THREE: Find d when t = 5</u>
<em>Given expression</em>
d = 2t
<em>Substitute value into the expression</em>
d = 2 (5)
<h2>d = 10</h2>
Hope this helps!! :)
