Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in 3 hours and 6 minutes?

Daniel [21]

Jordan will cover $26\frac{13}{15}\ miles$ in 3 hours and 6 minutes.

Step-by-step explanation:

Given,

Speed of Jordan = $8\frac{2}{3}=\frac{26}{3}\ mph$

Time = 3 hours and 6 minutes.

Converting minutes into hour.

6 minutes = $\frac{6}{60}\ hour = \frac{1}{10}\ hour$

Therefore;

Time = 3+ $\frac{1}{10}$ = $\frac{30+1}{10} = \frac{31}{10}\ hours$

Distance = Speed * Time

Distance = $\frac{26}{3}*\frac{31}{10}$

Distance = $\frac{806}{30}=\frac{403}{15}$

Distance = $26\frac{13}{15}\ miles$

Jordan will cover $26\frac{13}{15}\ miles$ in 3 hours and 6 minutes.

Use exact numbers. Complete the equation of the line through ( 2 , 1 ) (2,1)left parenthesis, 2, comma, 1, right parenthesis and

Anastasy [175]

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (5, - 8)

m = $\frac{-8-1}{5-2}$ = $\frac{-9}{3}$ = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 1) , then

1 = - 6 + c ⇒ c = 1 + 6 = 7

y = - 3x + 7 ← equation of line
