  1. speed of slower car --- x km/h
    speed of faster car ---- x+5 km/h

    When they meet, each will have gone for 12 hrs

    12x + 12(x+5) = 288
    24x = 228
    x = 9.5

    slow car went 9.5 km/h, the faster went 14.5 km/h

    check:
    12(9.5) + 12(14.5) = 288 , the answers are correct mathematically

    A poorly designed question, the answers are not realistic
