A, who travels 4 miles an hour starts from a certain place 2 hours in advance of B, who travels 5
irakobra [83]

It will take B 8 hours to travel in order to overtake A.

The relationship among the distance, time and speed can be expressed by using the relation.

\mathbf{speed = \dfrac{distance}{time}}

In this kind of ratio relation, it is pertinent to understand that, the rise in a variable cause a decrease in the other, where the third variable is constant.

Here:

  • as speed (v) rises;
  • time (t) decreases, and
  • distance (d) is constant

From the given relation:

  • Distance = speed × time

So, we can have a table expressing the parameters given in the question as follows:

           v            t            d

A          4            t+2     4t + 8

B          5             t         5t

Equating both distance together, we have:

4t + 8 = 5t

collecting like terms, we have:

4t - 5t = -8

t = 8 hours

Therefore, we can conclude that it will take B 8 hours to travel in order to overtake A.

Help please!!!! I will reward with 50 points
prohojiy [21]

Answer: The PIE strategy is the full form of Point, Illustration, and Explanation. When writing an essay, a paragraph, or a report, employ the PIE method. The acronym aids a writer in effectively stating the details of a topic.

Amy Tan employs imagery to convey her anxiety that Robert and his family will dislike her and her family's lunch, as well as that Robert will dislike her. Tan uses negative words to describe all of the meals, such as "black veins," "rubbery white," and "dry fungus." She is criticizing the meal, yet they are actually her favorite foods. This demonstrates that she is claiming to dislike her traditional foods because she is concerned that they will be too foreign to Robert.

What is the value of x?<br> (geometry question)
andreyandreev [35.5K]

<u>Given</u>:

The interior angles of the triangle are 44°, 3t - 45° and x - 15°

The exterior angle of the triangle is 4t - 29°

We need to determine the value of x.

<u>Value of t:</u>

The value of t can be determined using the exterior angle theorem.

Applying the theorem, we have;

44+3t - 45=4t-29

         3t - 1=4t-29

        -t - 1=-29

              -t=-28

                t=28

Thus, the value of t is 28.

<u>Value of x:</u>

The exterior angle 4t -29 and the interior angle x - 15 are linear pairs.

Since, linear pairs add up to 180°, we have;

4t-29+x-15=180

Substituting t = 28, we get;

4(28)-29+x-15=180

  112-29+x-15=180

                   x+68=180

                           x=112

Thus, the value of x is 112.
