trip 1 : 4

Given Distance:

trip 1 : \frac{1}{2}

trip 2 : 2

Represent the speed in terms of

x :

trip 1 : x

trip 1 Speed x Time 4 Distance \frac{1}{2}

Write an equation for trip 1Distance = Speed

\cdot

Time

\frac{1}{2} = x \cdot 4

Resolver para

x, \frac{1}{2} = x \cdot 4 : x = \frac{1}{8}

speed : \frac{1}{8}

Represent the time in terms of

y :

trip 2 : y

trip 2 Speed \frac{1}{8} Time y Distance 2

Write an equation for trip 2Distance = Speed
