Question

Time Remaining56:19m:s 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

x = Total distance from your home to school = 1,500 meters

Explanation:

Let

x = Total distance from your home to school

When you walked 20% of the way to school, you still have 1200 meters more to walk

Walked distance = 20% of x

= 20/100 * x

= 0.2 * x

= 0.2x

Total distance - walked distance = 1200 meters

x - 0.2x = 1200

0.8x = 1200

x = 1200 / 0.8

x = 1,500 meters

x = Total distance from your home to school = 1,500 meters
