Answer:
Car A speed = 80 m/s
Car B speed = 60 m/s
Step-by-step explanation:
Let Speed of Car A be represented as x
Let Speed of Car B be represented as y
- 280 = (x+y)(2)
- 140 = x+y --> Equation 1
Let z represent the distance that Car A travels until it catches up to Car B
Since it takes 14 hours for Car B to cover the distance z,
- 280 = 14(x-y)
- 20 = x-y --> Equation 2
Solving Equation 1 and Equation 2, we get:
- x = y+20
- 140 = 2y+20
- 120 = 2y
- y = 60
- x = y+20 = 80
