To find a speed in miles per hour, we need to divide a number of miles by a number of hours.
We are given 48 miles, so we already have a number of miles.
We are given the time as 1 hour and 12 minutes. We need to convert this time into hours.
1 hour + 12 minutes = 1 hour + 12/60 hour = 1.2 hours
speed = distance/time = 48 miles / 1.2 hours = 40 mph
Answer: The fourth choice, 40 mph.
Considering the perimeter of the rectangle, we have that the length is of 9 inches and the width is of 55 inches.
<h3>What is the perimeter of a rectangle?</h3>
The perimeter of a rectangle of length l and width w is given as follows:
P = 2(l + w).
The length is an odd integer and the width is <u>5 times the next consecutive odd integer,</u> hence:
l = x, w = 5(x + 2).
The perimeter is of 128 inches, hence:
128 = 2l + 2w
128 = 2x + 10(x + 2)
128 = 2x + 10x + 20
12x = 108
x = 9.
Hence the length is of 9 inches and the width is of 55 inches.

12 - 23 = -11
-11 + 1,345 = 1,334
1,334/123 = 10.85
Answer:
H: 2.8
Step-by-step explanation:
first divide 16 by 20 then you get a decimal.
then you add the decimal answer to the whole number (2)
Answer:
x = 8
Step-by-step explanation:
Complimentary angles are angles that add up to 90 degrees. If ABC and DBC are complimentary, then when added together, it equals 90 degrees.
ABC + DBC = 90
6x+13+4x−3 = 90
10x+10 = 90
10x = 80
x = 8
