The river that you swam in had a constant current of $0\mathrm{.}5\frac{m}{s}.$ You swam a distance $0\mathrm{.}8km$ up the river and back

down it to your initial position.

$($a$)$Find your velocity as you:

$($i$)$ Swim up river:

$u_{up}=$

Units are required for this answer. hat$(i)$

$($ii$)$ Swim down river:

$u_{\text{d}\text{o}\text{w}\text{n}}=$

$($b$)$ What is the time it takes you to:

$($i$)$ Swim up river:

$t_{up}=$

$($ii$)$ Swim down river:

$t_{\text{d}\text{o}\text{w}\text{n}}=$

$($c$)$ How long does the trip, there and back again, take in minutes?

$t=$

$($d$)$ What is your average speed while swimming in the river?

$\frac{?}{\text{b}\text{a}\text{r}}(v)=$
