Answer:
2000 m
Explanation:
When you have walked 20% of the way, you have 80% remaining. The difference between 80% remaining and 20% remaining is 60% of the distance, which is said to be 1200 metres.
The distance d is then given by ...
0.60d = 1200 m
d = (1200 m)/0.6 = 2000 m
The distance from home to school is 2000 metres.
