To start this question, put all of the terms in the same unit. Yards and feet aren’t equivalent, but a simple multiplication can put them in the same unit (1 yard = 3 feet).
60 feet in 1.5 hours vs. 90 feet in 2.5 hours
Now, put the distance travelled by each in the same amount of time. You can reduce these to one hour each, or you can multiply both by a common denominator to save some fraction work (the first CD I can calculate is 30 hours, so multiply each fraction by the necessary number to bring the denominator to 30).
(60 feet/1.5 hours) x 15 = 900 ft/30 hours
(90 feet/2.5 hours) x 12 = 1080 ft/30 hours
1080 feet in 30 hours is greater than 900 feet in 30 hours, so 90 feet in 2.5 hours is faster than 20 yards in 1.5 hours.
Hope this helps!

- Approximate Circumference = 43.96
- Exact Circumference = 43.982297
Step-by-step explanation:
Formula <u>U</u>sed: C=2πr
Step 1:
Divide Diameter by 2.
14ft / 2ft = 7ft
Radius = 7ft
<u><em>Explanation:</em></u>
The radius is the length from one inner side of a circle to the middle. While the diameter or a circle is the entire length across!
Step 2:
Multiply 7 (radius) times 3.14 (approximate pi) times 2
7 x 3.14 x 2 = 43.96
Approximate Circumference = 43.96
<u><em>Explanation: </em></u>
The question states that you are to find the approximate circumference <u>AND</u> the exact circumference. The difference is pi. You may have seen the pi symbol on your calculator when calculating exact circumference. It looks like this π. But sometimes we are asked to find the "not exact circumference" that is called the 'approximate' circumference. The not so scientific pi is shortened to 3.14.
Step 3:
Multiply 7 times π times 2
7 x π x 2 = 43.982297
Exact Circumference = 43.982297
I hope this helps!
