Solution

trip 2 distance : 5.6

Solution steps

Given Time:

trip 1 : \frac{3}{4}

trip 2 : 1

Given Distance:

trip 1 : 4.2

Represent the speed in terms of

x :

trip 1 : x

trip 1 Speed x Time \frac{3}{4} Distance 4.2

Write an equation for trip 1Distance = Speed

\cdot

Time

4.2 = x \frac{3}{4}

Solve for

x, 4.2 = x \cdot \frac{3}{4} : x = 5.6

speed : 5.6

Represent the distance in terms of

y :

trip 2 : y

trip 2 Speed 5.6 Time 1 Distance y

Write an equation for trip 2Distance = Speed

\cdot

Time

y = 5.6 \cdot 1

Solve for

y, y = 5.6 \cdot 1 : y = 5.6

trip 2 distance : 5.6
