The first thing you should know is that there are properties for logarithms.
One of them is the following one:
Let a and b be numbers, by property of logarithms:
log (a * b) = log (a) + log (b)
Therefore, by applying the property shown we have:
log 8 + log 3 = log (8 * 3)
log 8 + log 3 = log (24)
the answer is
log 24

Answer:

The initial distance between Wade and Alexandra is 240ft.

They walk towards each other.

Alexandra walks twice as fast as Wade.

Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.

Then:

if Wade walks z ft, Alexandra walks 2*z ft.

So we have the equation:

Distance that Wade walked + Distance that Alexandra walked = 240ft
