"Mia jogs 3 kilometers in 20 minutes. There are about 0.6 miles in a kilometer. What is Mia’s approximate speed in miles per minute?A. 0.25 miles per minute
B. 0.09 miles per minute
C. 4 miles per minute
D. 11 miles per minute"

Answers

First we need to find Mia's speed (v) in km/min

v = distance travelled/ time
v = 3 km/20 minutes
v = 0.15 km /min

in order to convert the speed into mile/min, we need to use the conversion factor given in which for every kilometer, there is 0.6 miles.

v = 0.15 km/min *(0.6 miles/ km)
v =0.09 miles/min

therefore the speed in miles/min is 0.09 miles/min

How do I solve x over 6 + 4+15 ?

Answers

x/6 + 4 = 15

First, subtract 4 to both sides:

x/6 = 11

Now multiply 6 to both sides:

x = 66

$x/6+4=15 \n x/10=15 \n *10\ \ \ *10 \n x=150$

Which of the following is not the same as 13.6 milliliters? 0.136 dL 0.0136L 0.0136 dkL

Answers

Unitconversion is the conversion of one unit to another unit with its standardconversion.

1 ml = 0.001 L

1 ml = 0.01 dL

1 dkL = 10,000 ml

13.6 ml = 0.0136 L

13.6 ml = 0.136 dL

13.6 ml = 0.00136 dkL

Options A and B are the correct answer.

What is unit conversion?

It is the conversion of one unit to another unit with its standardconversion.

Example:

1 minute = 60 seconds

1 km = 1000 m

We have,

13.6 milliliters.

1 ml = 0.001 L

1 ml = 0.01 dL

1 dkL = 10,000 ml

Now,

1 ml = 0.001 L

13.6 ml = 13.6 x 0.001 L

13.6 ml = 0.0136 L

1 ml = 0.01 dL

13.6 ml = 13.6 x 0.01 dL

13.6 ml = 0.136 dL

10,000 ml = 1 dkL

1 ml = 0.0001 dkL

13.6 ml = 13.6 x 0.0001 dkL

13.6 ml = 0.00136 dkL

Thus,

13.6 ml = 0.0136 L

13.6 ml = 0.136 dL

13.6 ml = 0.00136 dkL

Options A and B are the correct answer.
