May someone solve this question?

Daisy drove a Corolla and made the 1500 km trip to Mathville in 5 hours less than Kelly who took a Greyhound bus that made the same trip. If the bus traveled 25 km/h slower than Corolla, then find the speed of the bus and the number of hours it took the Corolla.

Let Tc be the time it took the corolla to travel 1500 km. Let Tg be the time it took the bus to travel 1500 km. You need two equations to find Tc and Tg. You are given two facts. The difference between Tg and Tc is 5 hours, that should give you one equation. Can you use the other fact to derive a second equation?
