Astudent athlete runs 3 1/3 miles in 30 minutes a professional runner can run 1 1/4 times as far in 30 minutes how far can a professional runner run in 30 minutes

A student athlete runs miles in 30 minutes. A professional runner in 30 minutes can run times as far as a student.

1. Convert these fractions in following way:

2. Multiply them:

a professional runner can run miles in 30 minutes

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

40 x 50 = 2000
