Recall your d = rt, distance = rate * time.
bearing in mind that, when she's going downstream, she's not going 40 mph, she's going 40 + 4 mph, because the stream is adding its speed to it.
likewise, when she's going upstream, she's going 40 - 4 mph, because the stream is eroding speed from it, thus
so, "u" is 16 minutes and 40 seconds.
and "d" is 13 minutes and about 38 seconds.

Answer:
Therefore,
The Equivalent expression is option A,
Step-by-step explanation:
Given:
Expressions is
To Find:
Equivalent expression ?
Solution:
We have Law of indices
For option A
(1.08^t)^4
Hence option A is the Equivalent expression.
For option B
1.08^8t/1.08^2t
Which is not the Equivalent expression.
For option C
1.08^4*1.08^t
Which is not the Equivalent expression.
For option D
1.08^6t/1.08^2t
Which is not the Equivalent expression.
Therefore,
The Equivalent expression is option A,
