Alina Is Able To Swim At A Rate Of About 2.5 Miles Per Hour. Talia Is Able To Swim At A Rate Of 1.8 Meters Per Second. Which Statement Comparing The T

Alina is able to swim at a rate of about 2.5 miles per hour. Talia is able to swim at a rate of 1.8 meters per second. Which statement comparing the two swimmers is accurate? 1 mile 1,609 meters Alina swims about 0.7 miles per hour faster than Talia. Talia swims about 0.7 miles per hour faster than Alina. Alina swims about 1.5 miles per hour faster than Talia. Talia swims about 1.5 miles per hour faster than Alina.

  Given:
Alina= 2.5mi/hr
Talia= 1.8m/s
1mi=1,609m

As the options given are expressed in mi/hr then Convert Talias speed into mi/hr
Take note that 1hr = 3,600s
Talia:
= 1.8 \frac{m}{s} ( \frac{1mi}{1609m} )( \frac{3600s}{1hr} ) \\ = 4.03 \frac{mi}{hr}

Get the difference of Talias speed and Alinas
Talia-Alina
4.03mi/hr-2.5mi/hr = 1.53mi/hr or approx 1.5 mi/hr

Therefore Talia swims about 1.5mi/hr faster than Alina

4 Postues/Propositions Of The Modern Cells Theory

4 postues/propositions of the modern cells theory   There are three postulates of cell theory . These were organized knowledge and findings from many studies done on cells. Robert Hooke opened the doors to studying the cells when he discovered them in cork cells. Postulates were laid out after by succeeding scientists. The first two were laid out by cell theory scientists Schleiden and Schwann from their researches about plant and animal cells. Listed below are the postutes and their explanations. Cell is the basic unit of all lifeforms. The smallest unit of life is cell. All the functions of life begin and end in a cell. This means that all other objects that are not made up of cells are considered nonliving things. All organisms are composed of cells and are product of cells . Since cell is the starting point of life, it is best to conclude that all organisms are made up of cells. However, remember that there are organisms which are unicellular, they are still organisms though...
