Solution steps

Given Time:

trip 1 : 4

trip 2 : 3

Given Distance:

trip 1 : 260

Represent the speed in terms of

x :

trip 1 : x

trip 1 Speed x Time 4 Distance 260

Write an equation for trip 1Distance = Speed

\cdot

Time

260 = x \cdot 4

x, 260 = x \cdot 4 : x = 65

speed : 65

Represent the distance in terms of

y :

trip 2 : y

trip 2 Speed 65 Time 3 Distance y

Write an equation for trip 2Distance = Speed

\cdot

Time

y = 65 \cdot 3

Solve for

y, y = 65 \cdot 3 : y = 195
