Question

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.​

Answer 1

y = 8x

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)
