Answer:
x = or 14.78
Step-by-step explanation:
The lines are parallel, therefore, k(18) acts same as g(x)
That means that:
k(18) = g(x)
- 14 = + 24
- 14 - 24 =
- 38 =
38(7) = 18x
266 = 18x
266 / 18 = x
133 / 9 = x
x = or 14.78
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.
