Question

The relationship between the distance run and the time for Amy can be represented by the equation Y equals 17.45X, where she ran Y meters in X seconds. which two equations could be used to represent the relationship for Brandon and Ruben

Answer 1

Brandon : Y = BX, where B is the speed (positive integer) and X is the time in seconds.

Ruben : Y = RX, where R is the speed (positive integer) and X is the time in seconds.

Explanation:

For Amy, the relationship between the distance run and the time taken is represented by the equation Y equals 17.45X, where she ran Y meters in X seconds.

Therefore we have,

Y = 17.45X

Y/X = 17.45 m/s, where m/s is meter per second.

Let us assume that the speed for Brandon is represented by B and that of Ruben is represented by R.

For Brandon, we obtain Y/X = B m/s

Y = BX

For Ruben, we obtain Y/X = R m/s

Y = RX

Answer 2

Question;

Assumption:

Let us assume Brandon's running speed is = 18.30 and

Ruben's running speed is = 16.50 and

Answer:

The two equations that can represent the relationship between the meters and second for Brandon and Ruben are;

Brandon → Y₁ = 18.3·X₁ and

Ruben → Y₂ = 16.5·X₂

Explanation:

The equation is of the form

Y = 17.45·X

That is Amy ran Y meters in X seconds

Therefore we have

`17.45 = (Y)/(X)` or the value 17.45 is the running speed of Amy

Therefore, where the running speed of Brandon is 18.30 and the running speed of Ruben is 16.50 we have

Y meters ran by Brandon in X seconds given by

Y₁ = 18.3·X₁ and

For Ruben we have Y meters ran in X seconds given by

Y₂ = 16.5·X₂.
