Marta has gone for a walk and has covered three quarters of the total route so far. If she still has 2 kilometres to walk, how long is the total route?

The total route is 8 kilometers.

Step-by-step explanation:

Let the distance of the total route be x

Marta has gone for a walk and has covered three quarters of the total route so far. This means that she has covered a distance of

3/4 * x = 3x/4 kilometers

she still has 2 kilometres to walk. This means that the total route or distance = the sum of the distance that she covered already and the distance she has remaining. Therefore,

x = 3x/4 + 2

x - 3x/4 = 2

(4x - 3x) / 4 = 2

Cross multiplying

4x - 3x = 4 * 2

x = 8

The total route is 8 kilometers.
