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 = $\dfrac{Distance}{Time}$

So, speed of red horse = $\dfrac{1}{120}\text{ mile per second}$

Since 1 mile = 5280 feet

Speed of red horse = $\dfrac{5280}{120} =44\text{ feet per second}$

Similarly,

Speed of black horse = $\dfrac{5280}{150} =35.2\text{ feet per second}$

Hence, the speed of red horse = 44 feet per second and the speed of black horse = 35.2 feet per second.

What is the solution to the following question?

alekssr [168]

1/3p+1/3x9=3+2p-12
1/3p+3=-9+2p
1/3p-2p=-9-3
1/3p-2p=-12
Now we put all the number under the common denominator 3 and we multiple -2p and -12 by 3
And this equals to:
1p-6p=-36
-5p=-36/x(-1)
5p=36
P=36/5
