Answer: The speed of red horse = 44 feet per second and the speed of black horse = 35.2 feet per second.
Step-by-step explanation:
Given: A red horse and a black horse raced on a 1-mile-long circular racetrack.
Time taken by red horse = 120 seconds
Time taken by black horse = 150 seconds
Speed = ![\dfrac{Distance}{Time}](https://tex.z-dn.net/?f=%5Cdfrac%7BDistance%7D%7BTime%7D)
So, speed of red horse =![\dfrac{1}{120}\text{ mile per second}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B120%7D%5Ctext%7B%20mile%20per%20second%7D)
Since 1 mile = 5280 feet
Speed of red horse = ![\dfrac{5280}{120} =44\text{ feet per second}](https://tex.z-dn.net/?f=%5Cdfrac%7B5280%7D%7B120%7D%20%3D44%5Ctext%7B%20feet%20per%20second%7D)
Similarly,
Speed of black horse = ![\dfrac{5280}{150} =35.2\text{ feet per second}](https://tex.z-dn.net/?f=%5Cdfrac%7B5280%7D%7B150%7D%20%3D35.2%5Ctext%7B%20feet%20per%20second%7D)
Hence, the speed of red horse = 44 feet per second and the speed of black horse = 35.2 feet per second.
Depends on what it is, i'd personally love to at any point
Write an algebraic expression that models the situation
Jenny had $177, but she is spending $25 per month.
The answer for this equation would be
177-25x
Answer:
See below
Step-by-step explanation:
= 2.449
So, While plotting to the number line it will be like:
Ratio being 3:5:7
longest being 56 so
7x=56
x=8
multiply the other lengths by 8
3*8=24
5*8=40
making the final
24:40:56
