2. Percy rides his bike 11.2 miles in 1.4 hours

at a constant rate. Write an equation to

represent the proportional relationship

between the number of hours Percy rides

x, and the distance in miles, y, that he

travels.

y = 8x

Step-by-step explanation:

If Percy rides x number of hours and the distance covered by her in miles is y, then the proportional relationship between y and x is given by the symbol

y ∝ x, ⇒ y = mx ... (1) {Where m is the constant of proportionality}

Now, given that Percy rides his bike 11.2 miles in 1.4 hours at a constant rate.

Then from equation (1) we get,

11.2 = 1.4m

⇒ m = 8 miles/hour

Therefore, the equation (1) will become y = 8x (Answer)
