10 minutes : 2.4 miles

Multiply both sides by 6 to get the distance per hour.

60 minutes (1 hour) : 14.4 miles

14.4 miles/hour

3*(4*3) = 3*4*3 = 36

A quadrilateral has 4 sides. Quadrilaterals include squares, rectangles, kites, rhombuses, parallelograms and trapeziums. They also have 4 vertices and an interior angle sum of 360 degrees.   

x*0.35 = 23

x = 23/0.35

x = 65.7 (1 decimal place)

Universe = Universe + 1 - 1 

20% of something is the same as mulitiplying something by 0.2  (20% = 20/100 = 1/5 = 0.2)

So 20% of 36000 is 36000 times 0.2 or divided by 5. Can you figure that out?

Thanks. It took me quite a few minutes to get my head around it. 

Yeah I haven't learnt that yet.

I did consider this.

$$\frac{5x+2}{2}=2x-1$$

$$5x+2=2{(2x-1)}$$

$$5x+2=4x-2$$

$$x=-4$$

Assuming that Earth's orbit is circular . . .

Circumference = pi times diameter

Since the sun is the center, the diameter is 2*93000000 = 186000000

C = pi*186000000 = 584336233.5677 miles.

So every 365 days Earth travels 584336233.567701542 miles.

Every 1 day it must travel 584336233.5677/365 =  1600921.187856717 miles.

And every hour 1600921.1878/24 = 66705.049494030 miles.

The speed is 66,705.05 miles/hour (nearest hundredth)
