Answer:

Speed of Car A is 80 km/h   and speed of Car B is 60 km/h.

Step-by-step explanation:

let v1 be speed of car A and v2 be speed of car B.

Then According to Question,

If they move in the same direction, then Car A will travel an ( x + 280 ) km while Car B will travel an x km. They both cover this in 14 hr.

using speed distance formula, we get

v1 × 14 = x + 280  

v2 × 14 = x  

v1=\frac{x}{14}+\frac{280}{14}=\frac{x}{14}+20  

v2=\frac{x}{14}  

v1 = v2 + 20 .................(1)

Moving towards each other, they'll collectively cover 280 km in 2 hours.

2 × (v1 + v2) = 280  

2 × (v2 + 20 + v2) = 280   (from eqn (1))  

v2 + v2 + 20 = 140  

2 × v2 = 120  

v2 = 60  

v1 = 60 + 20 = 80  

Therefore, Speed of Car A is 80 km/h   and speed of Car B is 60 km/h.

-62 + 18y = 264<br> -12x - 36y = 130<br><br><br> What solution is this
sergeinik [125]

Answer: x = -\frac{391}{6} =\\-65 \frac{1}{6}\\ -65.166666667\\y=\frac{163}{9}=18\frac{1}{9}  \\18.111111111

Step-by-step explanation: Multiply -36 and 163/9 to get -652. Add 652 to both sides then add 130 and 652 to get 782. Divide both sides by -12 then reduce the fraction 782/-12 to lowest terms by extracting and canceling out 2. The system is now solved.
