Answer:
[tex]xy=wz[/tex]
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = [tex]y[/tex] km/min
Time taken up the hill = [tex]x[/tex] minutes
Speed of Wilmer down the hill = [tex]z[/tex] km/min
Time taken up the hill = [tex]w[/tex] minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
[tex]Distance = Speed \times Time[/tex]
Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]
Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
[tex]xy=wz[/tex]
