Let's see who's semi intelligent.

show your work, fags.

>nautical speed in mph
who fucking does that?

is this a bait

>semi intelligent

Nigger this requires knowledge of physics and / or calculus or statistics or some shit

What do we look like?

5mp/h?

do your own homework, kid.

5 mph

miles per hour
MILES PER HOUR

I reject working with this, also reason why american scientist sucks dick compared to others

Stop trying to get people to do your homework for you mong

5
dont need to show work its so ez

70/60 = 1 1/6 hours
the river pushed the boat 70+80 miles back over the 1 1/6 hour time period, aka river speed = 150/(1 1/6) = something I cant be bothered to calculate

kill yourself

>count by 10s, so much easier
>easier
claiming easier is better. SMH cancer

Oh fuck me too

not about the part being easier, its standard values used by (nearly) everyone except some tards

Op here, none of you are correct so far.

4mph

It's still

56/60 = 0.93333333333
0.93333333333(miles per minute) x 75 (minutes) = 70 (miles)

64/60 = 1.06666666667
1.06666666667(miles per minute) x 75 (minutes) = 80 (miles)

The river is flowing at 4mph.

winrar

I'm sure there's an easier way to calculate that but that's how i worked it out.

>show your work
Fuck you. If I can just look at a problem and have the answer pop out of my brain I shouldn't have to fucking waste time writing all that shit out. Not that I could answer this question off the top of my head but I would always get so pissed about "show your work" in school.
