Question

Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50 miles in 4 hours. Find the constant of proportionality and write an equation to describe the situation. Let x represent the number of hours. The constant of proportionality is k = 12.5 The equation that describes the relationship is y =

Answer 1

$\begin{gathered} K=\frac{25}{2}=12.5 \\ K=\frac{37.5}{3}=12.5 \\ K=\frac{50}{4}=12.5 \\ y=kx \\ \text{Where y is the distance, x is the time and K is the proportionality} \\ y=12.5x \end{gathered}$
