The answer to the question is 21/100
To get to the end of the trail it would take 2 hours because the walking back hours would be double the walking out rate, but it would still have to equal 6 hours. So walking out would be 2 hours and walking back would be 4 hours which makes the trail 8 miles long.
Answer:
No, You can't. You have to make their denominators equal!

Step-by-step explanation:
So first, you make their denominators equal!

Multiplying both the numerator and denominator with the same number results in the same fraction, just un-simplified
So, we input it!

There you go!
Hope you get better at math!(gets wayyyyyyyyyyy...y more complicated later)
Hope this helps!
See Ya!

Answer:
h = 5
Step-by-step explanation:
area = 1/2 base × hight
base = 3 +h
hight =9 + 6 = 15
60 = 1/2 × 15 × (3+h)
120/15 = 3 + h
8 = 3 + h
h = 5
