Solution

trip 2 distance : 960

trip 1 speed : 120

trip 2 speed : 120

Solution steps

Given Time:

trip 1 : 5

trip 2 : 8

Given Distance:

trip 1 : 600

Represent the speed in terms of

x :

trip 1 : x

trip 1 Speed x Time 5 Distance 600

Write an equation for trip 1Distance = Speed

\cdot

Time

600 = x \cdot 5

Solve for

x, 600 = x \cdot 5 : x = 120

speed : 120

Represent the distance in terms of

y :

trip 2 : y

trip 2 Speed 120 Time 8 Distance y

Write an equation for trip 2Distance = Speed

\cdot

Time

y = 120 \cdot 8

Solve for

y, y = 120 \cdot 8 : y = 960

trip 2 distance : 960

trip 1 speed : 120

trip 2 speed : 120
