umka21 [38]

The distance traveled by first car is 50t + 100.

The distance traveled by second car is 70t.

The distance between the two cars after time, t is d = 100 - 20t.

The ratio of the distance traveled by the cars is (70t) / (50t + 100).

<h3>Distance traveled by each vehicle is calculated as follows;</h3>

The distance traveled by each vehicle at the given time is calculated as follows;

<h3>Distance traveled by first car</h3>

D₁ = speed x time

D₁ = 50(t + 2)

D₁ = 50t + 100

<h3>Distance traveled by the second car</h3>

D₂ = 70t

<h3>Distance between the two cars after time, t</h3>

d = D₁ - D₂

d = (50t + 100) - 70t

d = 100 - 20t

<h3>Ratio of the distance traveled by the cars</h3>

D₂/D₁ = (70t) / (50t + 100)

Are you trying to solve for x and y?

y=2x+1; x+2y=17
sub in one variable in the other equation.
x+2(2x+1)=17
x+4x+2=17
5x=15
x=3

now that you have x value, plug into the original equation to find y and check with the other. 
y=2(3)+1 = 7
x+2y=17 = 3 + 2(7) = 17 ; 17=17
