How much is time worth?Algebra Level 3
We were in a hurry so we decided to fill up on the way. 55 km. later we filled up with 40 litres at 124.9 c/l.
We got to our destination 500 km. later and filled up at 123.9 c/l.
If our car used 7 litres/ 100 km what was the cost per minute for leaving early? (cents/minute)(to 3 decimal places)
