The answer is D. When you have an exponent in a log, you can take the exponent down:
5 * logBASE4(4)
When you have a log base to the same number as the base, it’s always 1.
5*1 is .
speed of a boat when it goes downstream is 336/12 = 28 mi/h
speed of a boat when it goes upstream is 336/14 = 24 mi/h
Let v is speed of the boat in still water and x is speed of the current. Then,
v + x = 28
v - x = 24
Solve the system for v and x and get v = 26 mi/h, x = 2 mi/h
