Answer:
Each packet gives you 18 sticks of gum. If you asked how many in 5 packets it would be 90 sticks.
Using the <em>system of equation</em> created, Emily will catch up Lucy after 30 seconds
Given the Parameters :
- Lucy's distance = 2t
- Emily's distance = 5t
<u>We can set up an equation to represent the required scenario thus</u> :
Emily's distance = Lucy's distance + 90
5t = 2t + 90
We solve for t
<em>Collect like terms</em> :
5t - 2t = 90
3t = 90
Divide both sides by 3 to isolate t
t = 90/3
t = 30
Therefore, Emily will catch up with Lucy after 30 seconds

Step-by-step explanation:
the displacement is zero
128 I think
200 - 20 = 180
20 divided by 8 = 2.5
180 divided by 2.5 = 72
200 - 72 = 128
