When you walk in a direction and later walk opposite, you can substract both. So
15-3= 12km. Now we use Pythagoras. a2+b2=c2, c being the
hypotenuse. 144+81= 225. Sqrt this and you get 15 km.

Step-by-step explanation:
1. 5(2d+4)=35 -> multiply 5 to (2d+4)
2. 10d + 20 = 35
3. Subtract 20 by both sides

10d = 15
4. divide 10 by both sides
d = 15/10
d = 3/2
