Answer:
3/5 kilometer
Explanation:
there is 3 km and five friends and so to do that you can go ahead and just do the fraction 3 / 5
this makes aense because whenever you multiply 5 friends * 3/5 km that equals 15 / 5 the denominator doesn't change only the numerator so here 15/5 is 3 and therefore you end up with three kilometres again. and so your answer is going to be 3/5 km.
