Remember that d = rt or distance = rate times time.  You want your answer in miles per hour so convert 90 minutes to 1.5 hours.  Now plug in your values:
25mi = r*1.5hrs.
r = 25/1.5 = 16.667mph.

This is greater than 16mph so you did break your record pace.

Pierce is making a rectangular frame for a photo collage that has a perimeter of 72.2 72.2 inches. The length of the frame is 20
Allushta [10]

Answer:

P = 2x+2y   (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

P-2y = 2x

\frac{P-2y}{2} =x

And replacing we got:

x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in

And the width for this case would be 15.8 in

Step-by-step explanation:

For this case we know that the photo is rectangular. Let's define:

x = the width,  y= the length

And we know that the perimeter is given by:

P = 2x+2y   (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

P-2y = 2x

\frac{P-2y}{2} =x

And replacing we got:

x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in

And the width for this case would be 15.8 in
