Need help please :D i have a picture of the problem attached. :D
suppose to find the swimmers speed relative to the water if he went from a to b
@amistre64
got a slow internet connections at the moment, waiting for gyazo to load
okay no problem
i dont see a question, just relative information
yea i wrote what we need to find in the comments part
need to find the swimmers speed relative to the water if he swam directly from a to b
suppose to find the swimmers speed relative to the water if he went from a to b so we are to assume the path taken across the river was from A to B,
yes
what is the distance from A to B
250 right?
maybe, sqrt(200^2+150^2) = 250 yes, what is the angle at A?
like 36.9?
im getting an idea ... spose we are just floating dead in the water, how long does it take to travel the distance of d2?
30
oops thts wrong gotta convert units
1.8 seconds?
.03 hours times 5 km/hr = .15 km
.03 hours is 1.8 seconds
1.8 minutes ... yes now if we were swimming straight across, from A to C, in order to hit B in .03 hours, how fast would we need to be swimming? just to give us a sense of how to work the problem
yeaminutes my bad lol
how would u find that out?
well, we need to cover 200 meters in .03 hours .... how do we calculate a rate?
6m/hr?
.2 km in .03 hours .... rate is measured in km per hour right? rate = km/hr
yea ok
