a person runs at a constant speed of 9.2 miles per hour for 6 minutes and 30 seconds. How far did they travel in yards.

ipn [44]

Given:

Speed $= \bold{9.2 \ \frac{miles}{hour}}$

$\therefore \\\\$

1-hour= 60 minutes

1-minutes=60 second

1-hour= 3600 second

Converting the given time into seconds:

Time= 6 minutes and 30 second

$=\bold{6\times 60 \ second + 30 \ second }\\\\=\bold{360\ second+30\ second}\\\\=\bold{390\ second}\\\\$

When 3600 seconds covers=9.2 miles

Then equation:

$=\bold{\frac{9.2}{3600}}\\\\$

390 seconds covers:

$=\bold{\frac{9.2}{3600}\times 390 \ miles} \\\\$

Let

$\bold{1 \ miles= 1760\ yard}\\\\$

Convert the traveling value into yards:

$=\bold{ \frac{9.2}{3600}\times 390\times 1760}\\\\=\bold{ \frac{9.2}{36}\times 39\times 176}\\\\=\bold{ \frac{9.2}{12}\times 13\times 176}\\\\=\bold{ \frac{9.2}{12}\times 2288}\\\\=\bold{ 9.2\times 190.66}\\\\=\bold{ 1754.072\ yards}\\\\$

Therefore, total traveling yards are"1754.072".

What is the domain and range of each relation?

LUCKY_DIMON [66]

Answer:

$\text{Domain of}R_1=\{-2,0,2,4\}$ and $\text{Range of}R_1=\{-3,-1,0\}$

$\text{Domain of}R_2=\{-3,-1,0,3\}$ and $\text{Range of}R_2=\{-1,0,1,2,3\}$

Step-by-step explanation:

Domain is the set of input values or x-values.

Range is the set of output values or y-values.

According to the relation mapping diagram, the relation is

$R_1=\{(-2,-3),(-2,-1),(0,0),(2,0),(4,-3)\}$

So,

$\text{Domain of}R_1=\{-2,0,2,4\}$

$\text{Range of}R_1=\{-3,-1,0\}$

In the graph 5 points are plotted. So, the relation is

$R_2=\{(-3,1),(-1,-1),(0,0),(3,2),(3,3)\}$

So,

$\text{Domain of}R_2=\{-3,-1,0,3\}$

$\text{Range of}R_2=\{-1,0,1,2,3\}$
