Amy was soaking her poor feet! together amy, marcus, and carrie walked a total of 15 miles in the wilbur school walkathon. marcus walked twice as far as carrie, and amy walked 3 times as far as carrie. how many miles did amy, marcus and carrie each walk?

First, model it out in an equation, and lets say x is the amount carrie walked

x+2x+3x=15

Then, combine like terms

6x=15

then divide

2.5

So now we have carries walk speed, then we go by the question, multiply 3 by 2.5 for amy, and 2 by 2.5 for marcus

carrie walked 2.5 miles

marcus walked 5 miles

amy  walked 7.5

answer: howdy

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
