Rapper DaBaby drove at a speed of 45 mph in front of Coosa High School on his way home from North Carolina. What was his speed i
NeTakaya
To find the answer, set up an equation:
\frac{45 \: miles}{1 \: hour}  \times  \frac{1000 \: meters}{1 \: mile}  \times  \frac{1 \: hour}{3600 \: seconds}  =
Using this set up we can cross out the units that are on opposite sides of the proportion such as miles and hours, leaving us with the desired units of meters and seconds. Then calculate m/s by multiplying 45 by 1000 meters and then dividing that value by 3600 seconds.

The resulting answer is 45mph = 12.5 m/s

A chemist needs 2,220 ml of potassium chloride to complete an experiment. She has 2 L. How many more liters does she need?
DerKrebs [107]

Answer:

  0.220 L

Step-by-step explanation:

One liter is 1000 mL, so 2,220 mL is 2.220 L. Subtracting the 2 L on hand gives the additional amount required:

  2.220 L - 2 L = 0.220 L

_____

The nice thing about metric units is that conversion factors are often powers of 10, so only movement of the decimal point is required. It can be worthwhile to become familiar with the SI prefixes.
