Mathew is watching a car race on TV. His favorite car covered 10 laps of 3.6 miles each in 18 minutes. What is average speed of the car in miles per hour?

Answers

In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
                                                     = 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
                   = 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
                           = 120 miles/ hour

explain why it is important to know if a time is in a.m. or p.m. when figuring out how much time has elapsed.

Answers

It is important because if you just so happen to go to sleep at 5:00 Pm and you wake up at 5:30 Am youd think only 30 minutes pass when in reality 12 hours and 30 minutes passed
it has to be pm I'm if it says for an example 5:00am you have to use pm now

wren wants to build a box to organize her scrapbook supplies.She has a stencil set that is 12 inches wide that needs to lay flat in tne bottom of the box.The supply box must also be no taller than 2 feet.Name one way she could build a supply box with volume of 72 cubic inches

Answers

Given:
Width 12 inches
Height 2 feet
Volume 72 cubic inches.

Volume = Length * Width * Height

We need to find the length of the box. But, we need to convert the height from feet to inches to find the length in inches.

1 foot = 12 inches

2 ft * 12 inches/1ft = 2 * 12 inches = 24 inches
Height should be 24 inches or less.

H < 24 inches

V = L * W * H
72 inches³ = L * 12 in * H
72 in³ ÷ 12 in = L * H
6 = L * H

Given the measure of 6 inches for Length and Height, these can be the combination:

1 * 6 = 6
2 * 3 = 6

V = L * W * H
72 in³ = 1 in * 12 In * 6 in
72 in³ = 72 in³

or 

72 in³ = 2 in * 12 in * 3 in
72 in³ = 72 in³

One way she could build a supply box with volume of 72 cubic inches is 12 in x 3 in x 2 in

Further explanation

A square is a regular quadrilateral, it has four equal sides and four equal angles (90-degree angles, or 100-gradian angles or right angles).

Wren wants to build a box to organize her scrapbook supplies. She has a stencil set that is 12 inches wide that needs to lay flat in the bottom of the box. The supply box must also be no taller than 2 feet. Name one way she could build a supply box with volume of 72 cubic inches.

Attached the picture of box with sizes 3in*12in*2in

V= 72 in^3\nV= 12 in*6in^2\nV= 12 in*3in*2in

Feet or foot written abbreviation ft is a unit of measurement, equal to twelve inches or 0.3048 metres, sometimes shown by the symbol ′

Volume is the quantity of 3-dimensional space enclosed by a closed surface, the space that a substance or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
