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

Veronika [31]

Answer:

He will bike 26.87 miles.

Step-by-step explanation:

Given:

Jordan bikes at a speed of 8 2/3 mph.

Now, to find the distance he will bike in 3 hours and 6 minutes.

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

Time = 3 hours and 6 minutes

= $180+6=186\ minutes.$

As, 60 minutes = 1 hour.

= $\frac{186}{60} =3.1\ hours.$

So, to get the distance we put formula:

$Distance=speed\times time$

$Distance=\frac{26}{3} \times 3.1$

$Distance=\frac{80.6}{3}$

$Distance=26.87\ miles.$

Therefore, he will bike 26.87 miles.

Solve the equation. (5x+7)(8x-9)=0

Lina20 [59]

Answer:

x = -7/5 and x = 9/8

Step-by-step explanation:

To solve this equation, set both parts of the "expression" equal to 0.

5x + 7 = 0

Subtract 7 from both sides.

5x = -7

Divide both sides by 5.

x = -7/5

8x - 9 = 0

Add 9 to both sides.

8x = 9

Divide both sides by 8.

x = 9/8
