Mick travelled one quarter of the way home from his holiday destination before he had to stop and get petrol. 100 kilometers further on, he still had 500 kilometers to go. how many kilometers is the petrol station from mick's holiday destination? a: 50 km b: 100 km c: 250 km d: 200 km e: 180 km plz explain how you got the answer.

Right, so the whole distance between the holiday destination and his home is going to be 4/4. If you take the 1/4 away from 4/4, you have 3/4. This means the distance between the petrol station and his home must be 3/4 of the way. The distance between the petrol station and his home is 500 + 100, which is 600. So 600 = 3/4 of his journey. To get 1/4 you just divide that by 3, so you get 200.
So the answer is D x
