.. Hiking the Appalachian Trail. The Appalachian Trail runs from Mt. Katahdin in Maine to Springer Mountain in Georgia, a total distance of 2160 mi. If you hiked for 8 h per day, estimate (a) how many steps it would take to hike this trail and b) how many days it would take to hike it.

a) $=5.79 \times 10^{6}$b) 1207 days

In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true. The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics.

In mathematics, algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

true. Okay, well, in the chapter one problem 57. So it says appellation Mayor Trail has a total distance of 2116 my holes. And it says if you hike for eight hours per day, how many steps would it take? A hike? This trail? I estimate that in how many days will it take to Taik? Okay, so first, let's estimate how many you going? A step. So we'll say each step because to fit seems about right. So one mile we know is 1 5,000 to 80 its feet. So if we want to figure out how many miles we go, must figure out how many feet are in here. So 2160 miles was convert to feet. So this is 5 to 80 feet over in one mile. So this is going to be 5.7. I'm sorry, I'm come to have a little bit. This is going to be 1.14 times 1.14 10 to 7 feet. And if this is how many total feet there are, each step is two feet. We just divide this by two, and that equals 57 times 10 to the six steps, So lots of steps to do, asshole. I think so is figure out the time it takes to require. So let's also estimate E that we can probably take about 100 steps a minute. And we shouldn't do eight hour today's 100 steps per minute since not right about walking a beat. So to figure this out we take the total number of steps I've pumped into the six steps and we can divide this by 100 steps per minute and you see the steps cancel out. We're left with 5.7 times 10 to the four minutes how long it takes. So now we know we can be paid hours a day, so it's convert this to ours. So in one hour they're 60 minutes, so this equals 950 hours. So if we conduce at all eight hours a day so 950 hours over eight hours per day, that comes out to 120 days, so it takes a very long time to walk its trail. You've got to be very committed, any for me. Cool
