Answer:

21.5 miles total

Step-by-step explanation:

First, identify what you know:

1) Mike can run 4 mph, and runs a total of 1 hour, and 45 minutes (105 min)

2) Chris can run 6 mph, and runs a total of 70 minutes.

3) John can run 5 mph, and runs a total of 1 hour, and 30 minutes (90 min)

We need to calculate how many miles each person ran, and then add the miles ran, to find the total!

Mike: 1 hour and 45 minutes it equal to 1.75! So, in one hour, Mike ran 4 miles. He ran 3/4 of 4 mph, in 3/4 of an hour! Thus, Mike ran 7 miles. Simply multiply 1.75 by 4, to get 7 mph.

Chris: Chris ran 6 mph for 70 minutes. 6 mph, means that Chris can run one mile per every ten minutes! In 70 minutes, he'll have run 7 miles.

John: If john ran 90 minutes, that means he ran 1.5 hours! Simply multiply 1.5 by 5 mph, to get 7.5 miles!

Now, all we need to do, is add the totals!

7 + 7 + 7.5 = 21.5

In total, Mike, Chris, and John ran 21.5 miles!

Hope this helps! :)

Find, correct to four decimal places, the length of the curve of intersection of the cylinder 16x2 + y2 = 16 and the plane x + y

Yuri [45]

Let the curve C be the intersection of the cylinder

$16x^2+y^2=16$

and the plane

$x+y+z=1$

The projection of C on to the x-y plane is the ellipse

$16x^2+y^2=16$

To see clearly that this is an ellipse, le us divide through by 16, to get

$\frac{x^2}{1}+ \frac{y^2}{16}=1$

$\frac{x^2}{1^2}+ \frac{y^2}{4^2}=1$ ,

We can write the following parametric equations,

$x=cos(t), y=4sin(t)$

for

$0\le t \le 2\pi$

Since C lies on the plane,

$x+y+z=1$

it must satisfy its equation.

Let us make z the subject first,

$z=1-x-y$

This implies that,

$z=1-sin(t)-4cos(t)$

We can now write the vector equation of C, to obtain,

$r(t)=(cos(t),4sin(t),1-cos(t)-4sin(t))$

The length of the curve of the intersection of the cylinder and the plane is now given by,

$\int\limits^{2\pi}_0 {|r'(t)|} \, dt$

But

$r'(t)=(-sin(t),4cos(t),sin(t)-4cos(t))$

$|r'(t)|=\sqrt{(-sin(t))^2+(4cos(t))^2+(sin(t)-4cos(t))}$

$\int\limits^{2\pi}_0 {\sqrt{2sin^2(t)+32cos(t)-8sin(t)cos(t)} }\, dt=24.08778184$

Therefore the length of the curve of the intersection intersection of the cylinder and the plane is 24.0878 units correct to four decimal places.
