galben [10]

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.

Two negative consecutive integers have a sum of -65. what are the integers?

Ede4ka [16]

Answer:

-32 and -33

Step-by-step explanation:

x + (x + 1) = -65

2x +1 = -65

2x = -66

x = -33. So (x + 1) = -33 + 1 = -32

-33 + -32 = -65
