Two cars start from the same place at the same time. After two hours, one car has traveled 30% farther than the other. If one car's speed is 20mph larger than the other car's speed, what are the speeds of the cars? Solve algebraically.

  • Phsyics -

    V2 = 1.3 V1
    V2 = V1 + 20

    Solve simultaneously.

    The first step might be

    0 = 0.3 V1 -20
    Solve for V1; then V2

  • Phsyics -

    how did you get 1.3?
