Answer:
Upstream = 0.5 hour.
Downstream = 0.366 hour.
Step-by-step explanation:
Speed of fram in still water (u) = 2.6 mph.
Speed of water (v) = 0.4 mph .
<h3>Time taken by fran to swim 1.1 mi upstream.</h3>
Speed upstream = u - v = (2.6 - 0.4) mph = 2.2 mph
So the time taken =
= 0.5 hour.
<h3>Time taken by fran to swim 1.1 mi downstream.</h3>
Speed downstream = u + v = (2.6 + 0.4) mph = 3 mph .
So the time taken =
= 0.366 hour .

Suppose the interest rate is 4%, the equivalent of $200 in one year will be:
A=P(1+r/100)^n
where:
p=principle amount
r=rate
n=time
Hence the amount in 1 year will be:
A=200(1+4/100)^1
A=$208
Therefore $200 today is equivalent of $208 in 1 year.
