Paula bicycled for 20 minutes and covered 5 miles. What is her speed in miles per hour?

1 answer:

7 0

In four minutes, Paula covered one mile. Because one hour is equivalent to 60 minutes, we can divide 60 by 4 to get the amount of miles she covered in an hour. 60 / 4 = 15, which means that Paula’s speed is 15mph.

$\longrightarrow \sf h) \:\:\dfrac{2}{3},0.67,70\%,0.8$

<h3><u>Solution:-</u></h3>

Let us first write all the provided number in decimal

$\quad\leadsto\sf \dfrac{2}{3}= 0.\bar{66}$

$\quad\leadsto\sf 70 \% = \dfrac{70}{100}$

$\quad\quad\quad\implies\sf 0.7$

$\quad\leadsto 0.67$

$\quad\leadsto 0.8$

<u>Comparing all the numbers </u><u>now </u><u>-</u>

$\longrightarrow \sf 0.\bar{66}$

$\longrightarrow\sf \dfrac{2}{3}$

Answer:

The correct option is C.

Step-by-step explanation:

The bike shop owner rents out bikes and scooters.

The cost to rent a bike is $15 plus $8 per hour for each hour the bike is rented.

Rent of bike = Fixed rent + Variable rent

The rent function of a bike is

$f(x)=15+8t$

Where, t is number of hours.

The cost to rent a scooter is $35 plus $5 per hour for each hour the scooter is rented.

The rent function of a scooter is

$f(x)=35+5t$

Where, t is number of hours.

The slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

So by slope intercept form the rate of change of bike is $8 and rate of change of scooter is 5.

8>5

Therefor option C is correct.
