Answer:

  30 hours

Step-by-step explanation:

The relation between time, speed, and distance is ...

  time = distance/speed

  time = (15 km)/(0.5 km/h) = 30 h

It takes 30 hours for the lava to reach the sea.

subset to real numbers, and as you can see are not at all connected to the rest of numbers (and integers).
Natali5045456 [20]

Irrational numbers are the subset of real numbers that are not at all connected to the rest of numbers.

The subsets of real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.

Natural numbers are subset of whole numbers, which are subset of integers, which are subset of rational numbers. Hence, all of them are interconnected. The set of irrational numbers is the only subset of real numbers which is not associated with the rest.

For example:-

1 is a natural number, whole number, integer, rational number but not irrational number. On the other hand, \sqrt{2} is an irrational number but none of the rest.

Jerry multiplied 3.04 x 7.091 and got the product 2.155664. Is his answer reasonable? Why or why not?
Readme [11.4K]

First we multiply the numbers ignoring the decimal and then place the decimal in the position

3.04 *7.091 = 2155664

Now the first number has two digits after the decimal and the second number has three digits after the decimal.

Therefore in the final result we have to move the decimal (2+3) =5 place from the left,

So the answer would be 21.55664

So, the correct answer is 21.55664

Jerry calculated the answer correctly , but made an error in the placement of the decimal point.  The answer is not reasonable because 2.155664 and 21.55664 mean two completely different answer far apart from each other
