A) What is the distance from the start to the end of the trail?
B) Louise walked from the start of the
trail to the bird lookout and back. Did
she walk a longer or shorter distance
than if she had walked from the start
of the trail to the end? Explain.
C)Another day, Louise walked from the
start of the trail to the end. At the end,
she realized she forgot her binoculars
at the bird lookout. She walked from
the end of the trail to the bird lookout
and back. What is the total distance
she walked?

A) 6 17/24

               B) She walked a longer distance. Walking to the bird lookout and back would be 7 6/8 miles (Or 7 3/4 when simplified) while walking the full distance would be about 1 mile less.

               C) 3 7/8 + 2 5/6 =  6 17/24

          6 17/24 +(2 5/6 + 2 5/6) = 99/8 = 12 3/8

The Final answer is 12 3/8

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
