Question

When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.

How far, in metres, is it from my home to my school?

Answer 1

9514 1404 393

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.
