total journey

Answer 1

Find the fraction of the journey left:

1 - 3/4 = 1/4

Find the distance of the total journey:

1/4 of the journey = 15 km

4/4 of the journey = 15 x 4 = 60 km

Answer: The whole journey is 60 km

Your answer is:

The total distance covered by me is 60 km.

$1 - \frac{3}{4} = \frac{1}{4 } \\ 15 = \frac{1}{4} \: of \: the \: total \: distance \\therefore \: 15 \times 4 = 60$
