Answer :
Final answer:
Chelsea traveled at a speed of 75 km/h.
Explanation:
Let's assume that Chelsea's speed is x km/h. Since Castel traveled 15 km/h slower, their speed is x-15 km/h. In three hours, Chelsea traveled 3x km and Castel traveled 3(x-15) km. The total distance between them is the sum of these distances:
3x + 3(x-15) = 405 km
Solving the equation:
6x - 45 = 405
6x = 450
x = 75
Therefore, Chelsea traveled at a speed of 75 km/h.
