A motorboat is capable of traveling at a speed of 12 miles per hour in still water. On a particular day, it took 30 minutes longer to travel a distance of 8 miles upstream than it took to travel the same distance downstream. What was the rate of current in the stream on that day?
The rate of current was
___mph on that day

d. 5

step-by-step explanation:

f(x) + n - shift a graph n units up

f(x) - n - shift a graph n units down

f(x + n) - shift a graph n units to the left

f(x - n) - shift a graph n units to the right

on the picture we can see:

the graph g(x) was made by shifting the graph f(x), 5 units to the left.

therefore g(x) = f(x + 5) → k = 5

look at the picture.
