There are 5,280 feet in 1 mile. if Riley ran 26,400 feet how many miles did she run

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
