Karla is training for a marathon she can run 2 miles and 16 minutes if she runs at that pace the whole race how long will it take her to run the entire marathon

We know that a marathon is 26.2 miles, so we can set up a proportion to solve for the time it would take her to run the entire marathon:

Then solve for x by cross multiplying:

So now we know it will take Karla 209.6 minutes to run the entire marathon, or, in hours, 3.49 hours.

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
