Marisel rode her bike against the wind for 1 hour and traveled 15 km. she returned te same distance with the wind in 36 minutes, what was the arte of the wind?

$18 was the price of the t-shirt

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
