x = total distance to travel, in km

The driver has done 115+85 = 200 km so far which is 80% of the way there.

Or as a slight alternative, we're solving the equation to get

The total distance s/he needs to travel is 250 km.

If the driver has done 200 km so far, then there's 250-200 = 50 km left to go.

Answer: c) 50

a)20 b)40 c)50 c)160 d)200

Distance travelled after day 2: 115 + 85 = 200 km With 80% of total distance already travelled, he/she has .2 or 20% (100% - 80%) left to travel, which results in the following PROPORTION: 4R = 200 ---------- Cross-multiplying Remaining distance to travel, or
