1. The problem statement, all variables and given/known data A bus travels 650km in 3 hours less than the other bus whose speed is 15 km/h slower than the speed of the first bus. A. Assemble the equation. B. Solve the equation and state the speeds of the buses. 2. Relevant equations 3. The attempt at a solution V = d / t Velocity of the first bus = Velocity of the second bus - 15; V1 = 650 / t2 - 3 Time of the first bus = Time of the second bus - 3; V1 - 15 = 650 / t1 + 3 I don't really know.
