The sum of two rational numbers is rational and the sum of a rational number and an irrational number is irrational what about the sum of two irrational numbers decide whether the sum of two irrational numbers is always rational always irrational or either rational or irrational depending on the case share your

The sum of two irrational numbers is always a irrational number

Step-by-step explanation:

You can take the number π+π and the result still is an irrational number,

you can also probe with a more common number like √2 and √3, thus, we always have an irrational result.

Remember, an irrational number is the one that can not be expressed as a fraction between two integers numbers, or has an infinite number of non repetitive decimals.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
