In proper paragraph form,explain the difference between the union and intersection of two sets.

Sophie [7]

The correct answer is:

The union of two sets is a combination of all elements from both sets. The intersection of two sets, on the other hand, is a set of the elements common to both sets.

For instance, if we have the sets {1, 3, 5, 7, 9} and {3, 6, 9, 12, 15}, the union would be the combination of both:

{1, 3, 5, 6, 7, 9, 12, 15}

The intersection of the sets would be the common elements. The only elements that are in both sets are 3 and 9. This makes the intersection

{3, 9}

If the average speed of a garden snail is 0.025 miles per hour and one inch is approximately 2.54 centimeters, how many minutes

Katen [24]

Answer:

Option B 1.5 min

Step-by-step explanation:

we know that

1 mi=1,609.36 m

1 h=60 min

$0.025\ mi/h=0.025(1,609.36)/60=0.67\ m/min$

using proportion

$\frac{0.67}{1}\frac{m}{min} = \frac{1}{x}\frac{m}{min}\\\\x=1/0.67\\\\x=1.5\ min$
