Tanner cycled 8 miles in 20 minutes .What is the constant of proportionality based on the situation
solmaris [256]

The constant of proportionality based on the situation is 0.4

Step-by-step explanation:

Tanner cycled 8 miles in 20 minutes

We need to find the constant of proportionality based on the situation

1. The distance is proportion to the time, because the distance and

   the time increased together

2. If the distance d and the time is t, then d ∝ t

3. The equation of the direct proportion is d = k t, where k is the

    constant of proportionality

∵ d = k t

∵ d = 8 miles

∵ t = 20 minutes

- Substitute these values in the equation above

∴ 8 = k (20)

- Divide both sides by 20

∴ k = 0.4

The constant of proportionality based on the situation is 0.4
