Answer:
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.
