Your question asks for an expression, so you would expect an answer in the form of an equation containing variables. This is because you have only 2 independent equations with 3 unknowns. That makes the system unsolvable.
Suppose v₁ is the mountaineer's velocity during the 1,000-foot trail. Then, v₂ is his speed for the 5,000-foot trail. The equation relating these two variables is:
v₂ = 2v₁ - 10 ---> equation 1
Then, you find the equation for the total number of hours he climbed. That would be the distance divided by their respective speed.
t = 1000/v₁ + 5000/v₂ ----> equation 2
Substituting equation 1 to equation 2,
t = 1000/v₁ + 5000/(2v₁ - 10)
t = 1000/v₁ + 5000/2(v₁-5)
t = 1,000/v₁ + 2,500/(v₁-5)
3o'clock - directly to the right of the origin; on the x axis - (5,0)
6o'clock - directly below the origin; on the y-axis - (0,-5)
9o'clock - directly to the left of the origin; on the x-axis, (-5,0)
12o'clock - directly above the origin; on the y-axis, - (5,0)
Answer:
Follows are the solution to this question:
Step-by-step explanation:
Following are the step which is used in the question:
- Step 1, In this use the sheet on the formulas tab we use the function, that is the part of the FLG "Function Library group".
- Step 2, In this step, click the Financial button, and after that click on the PMT.
- Step 3, after clicking on PMT apply or Enter the value that is "B3/12", in this it provides the rate argument box.
- Step 4, after insert value in B4, it provides the Naper argument box, that input the value in "B2" cell into the Pv argument box.
- Step 5, After click the OK button.
I’m not entirely sure but the answer might be 72 1/2 miles. I added up 12 1/3, 8 3/4, 17 2/8, 23 2/3, and 10 5/10. And I got 72 1/2.
