Adam and his older sister, Kelli, run a race. Adam runs 3 meters every second, and Kelli runs 5 meters every second. In a 100-meter race, Adam gets a 40-meter head start because he runs at a slower pace.

the answer to your question is c

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!
