    1. The problem statement, all variables and given/known data
    Magna is travelling at 110 kph, and realises Commodore in front of him is travelling at 80kph. To avoid a collision, what is the max speed the Magna can have as it reaches the commodore?

    2. Relevant equations


    3. The attempt at a solution
    I am not sure how to approach this.

    Hi,

    One way to approach this is to try a few numbers. Not extremely sophisticated, but it works to get a feeling. 100 ? 50 ?
