Question

after going 2/5 of my journey I find that I have covered 16 kms.....how much journey is still left

Answer 1

Consider your journey be divided into 5 parts. You have covered 2 parts. So consider the total distance to be travelled to be x km. So 16km = 2/5 * x. Therefore x= (5*16)/2. So x = 40km

Answer 2

In this question,
Let us assume total distance be x.
Now,
As per the question,
2/5 *x = 16
x = 16*5/2 = 40
So, Total distance = 40 Km
Distance he already covered = 16 Km
Thus, Rest distance = 40-16 = 24 Km.
