What is the unit of rate for page per hour?

Unit : pages per hour

We have the solution of

$\frac{10}{ \frac{1}{3} } = \frac{x}{1}$

Where the numerator is the number of pages and the denominator is the time

Multiply 10 by 1 and divide by ⅓

$\frac{10 \times 1}{ \frac{1}{3} } = \frac{10}{ \frac{1}{3} } = 30$

So she can read in a total of 30 pages per hour...

========================

Hours per page...

We have the equation

$\frac{10}{ \frac{1}{3} } = \frac{1}{x}$

Solve for x

$10x = \frac{1}{3} \\ \frac{10x}{10} = \frac{ \frac{1}{3} }{10} \\ x = \frac{1}{30}$

She can read one page in 1/30 hours or 2 minutes

Hope this helps =_=

Answer from: Quest

Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.
