Answer:
Step-by-step explanation:
If Elena walk 12 miles, and then 0.25 that distance
0.25=1/4
12*1/4=3 miles is 1/4 of the distance

The answer is (8,0)
that is the answer
Let,
Harry's age - x then Nick is 7x.
After 6 years, Harry is x+6 and Nick is 7x+6
So, 7x+6= 5(x+6)=> 2x = 30-6X = 12
In 6 years, Harry will be 12+6 = 18 years (Ans)
