Step-by-step explanation:
<em><u>Equation shows the relationship between distance traveled (d), speed (s), and time taken (t) is:</u></em>

<em><u>Solution:</u></em>
Given that,
Alice traveled 30 miles in 3 hours
<em><u>To find: Equation shows the relationship between distance traveled (d), speed (s), and time taken (t)</u></em>
<em><u>The speed is given by:</u></em>

From given,
Distance = d = 30 miles
Time = t = 3 hours
Therefore,


Thus the equation is found and speed is calculated
Answer:
Step-by-step explanation:
The smaller rectangle has a perimeter of 200 meters. Let's say that the smaller rectangle has length 60 and width 40. This would give it a perimeter of 200, since 2*(60+40) = 200.
If these are the length and width of the smaller one, we can multiply each by 5/4 to get the length and width of the larger one.
length of larger rectangle = 60*5/4 = 75
width of larger rectangle = 40*5/4 = 50
These dimensions would give a perimeter of 250, since 2*(50 + 75) = 250.
It is worth noticing that 250 is equal to 200 * 5/4. In the future, you can simply multiply perimeter by the ratio instead of going through all these steps.
