Based on the given situation above, the given values are 8 kilometers and 24 minutes. To simplify these values, we will come up with the result of 1 km in 3 minutes. Therefore, the winner of the New York marathon ran 0.33 kms per one minute so the runners unit rate is 0.33kms/minute.
The direct variation equation relates x and y is y =
x
Step-by-step explanation:
Direct variation is when one variable is equal to a constant times another variable
If y varies directly with x, then
- y ∝ x
- y = k x is the equation of variation
- k is the constant of variation
∵ y varies directly with x
∵ y ∝ x
∴ y = k x
∵ y = 10 when x = 3
- Substitute these values in the equation above to find k
∴ 10 = k(3)
∴ 10 = 3 k
- Divide both sides by 3
∴ k = 
∴ The equation of variation is y =
x

Answer:
I believe the answer is B. it is correct if it says, 1: 1,200
Step-by-step explanation:
Because the ratio is 1: 1,200
Multiply each exponent inside the parentheses by the exponent on the outside of the parentheses:
4/5 x 3 = 12/5
9 x 3 = 27
