Question

Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilometers per minute, and it took him w minutes to do it. Write an equation that relates x, y, z, and w. (The wording for this question really confuses me. And I do not understand which variable to put on it's own.) PLEASE ANSWER

Answer 1

xy=wz

Explanation:

Answer 2

`xy=wz`

Explanation:

Given that:

Speed of Wilmer up the hill =
`y` km/min

Time taken up the hill =
`x` minutes

Speed of Wilmer down the hill =
`z` km/min

Time taken up the hill =
`w` minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

`Distance = Speed * Time`

Distance up the hill =
`y* x =xy\ kilometers`

Distance down the hill =
`z* w =wz\ kilometers`

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

`xy=wz`
