<u>Answer:</u>

Mrs. Khan is mailing 2 packages. Subtract 623 – 312 best describe how to find out how much heavier the larger package is. Hence Option C is correct

<u>Solution:</u>

Given that  

Mrs khan is mailing two packages.

Weight of larger package = 623 pounds  

Weight of small package = 312 pounds

Now we need to find how much heavier larger package compare to smaller one is.

To get this if we remove weight of smaller package from larger package , we will get how much larger package is heavier.

That is<em> Weight of larger package – Weight of smaller package</em> = 623 pounds – 312 pounds

Hence option C) subtract 623 – 312 best describe how to find out how much heavier the larger package is.

Answer:

3.2 km/h

Step-by-step explanation:

1. Approach

The average speed is the rate at which one travels. It can be found by diving the total distance traveled over the total time it took to cover that distance. In essence, the following formula can be used to find the average speed:

\frac{total\ distance}{total\ time}=average\ speed

In this situation, one is asked to find the difference between two people's average speed. One is given the following information:

Lena: 24 miles          1.5 hours

Ras:   36km               1 hour 15 minutes

First, convert all of the numbers into the correct units (km) and (hours). Then find the average speed for each person. Finally, subtract the smaller speed from the larger speed to find the difference in the average speeds.

1. Find Lena's average speed

The problem asks one to find the average speed in the units (km/h). However, the distance Lena covered is given in (miles). Therefore, one has to multiply it by the conversion factor (1.6) in order to convert it from (miles) to (km).

24miles * 1.6 = 38.4

Now find the average speed by using the formula:

\frac{total\ distance}{total\ time}=average\ speed

Substitute,

\frac{38.4}{1.5}\\\\=25.6

2. Find Ras's average speed

Use a similar approach to work out Ras's average speed, as was used to find Lena's average speed. Since Ras's time spent is given in both hours and minutes, one must convert it to just minutes. There are (60) minutes in an hour, thus, one can rewrite the number as the following:

1\ hour \ \ 15\ minutes= 1 \frac{15}{60}\ hours = \frac{75}{60}\ hours

Now find the average speed:

\frac{total\ distance}{total\ time}=average\ speed

Substitute,

\frac{36}{\frac{75}{60}}\\\\=28.8

3. Find the difference between the speeds

Since Ras's speed is greater, subtract Lena's speed from Ras's speed.

Ras - Lena

= 28.8 - 25.6

= 3.2

yKpoI14uk [10]
I just had this question for homework too!

c = 4v + 1
v + c = 121

Now use substitution.

v + 4v + 1 = 121
5v + 1 = 121
5v = 120
v = 24

The answer is 24.
