    Answer: 80mph

    Explanation:

    Since the two cars are approaching each other, it can be said that:

    Speed of Car A moving from left to right = 30mph

    Speed of Car B moving from right to left = 50mph

    Now recall that relative speed of objects moving in opposite directions is equal to the sum of each speed

    Hence, Relative speed = (Speed of Car A + Speed of Car B)

    Relative speed = (30mph + 50mph)

    Relative speed = 80mph
