Hey!!
Let’s take the total distance as ‘x’
We have completed 13/17th of the trip.
We have 80 km left.
With this, we understand that :
13/17 th of the trip is total distance - 80
.... 13x/17 = x - 80
... 13x = 17x - 1360
... -4x =- 1360
... x = -1360 / -4
... x = 340.
340 km is the totla distance .
We have travelled 13/17 th.
... 13/17 * 340
... 13 * 20
... 260
Hence, the distance we have travelled is 260 km.
Hope my answer helps!!
