trip 2 distance : 612.5

Fasi della soluzione

Given Time:

trip 1 : 4

trip 2 : 7

Given Distance:

trip 1 : 350

Represent the speed in terms of

x :

trip 1 : x

trip 1 Speed x Time 4 Distance 350

Write an equation for trip 1Distance = Speed

\cdot

Time

350 = x \cdot 4

Risolvi per

x, 350 = x \cdot 4 : x = \frac{175}{2}

speed : \frac{175}{2}

Represent the distance in terms of

y :

trip 2 : y

trip 2 Speed \frac{175}{2} Time 7 Distance y

Write an equation for trip 2Distance = Speed

\cdot

Time

y = \frac{175}{2} \cdot 7

Risolvi per

y, y = \frac{175}{2} \cdot 7 : y = \frac{1225}{2}

\frac{1225}{2} = 612.5

trip 2 distance : 612.5
