Thanks - Glad you think so!

Regarding the last question. Won't the swimmer have to swim along the hypotenuse of the triangle theirby making the travel longer?

[@julial2918]

I was curious about this too

I think the problem is a bit confusing and not addressed properly, they are asking about how long it’ll take the swimmer to get to the other side. The swimmer will only swim across (the y) but the river will carry him in the x. You don’t need the x to solve for the time since he will just travel across from his point of reference. Sometimes questions will ask, how FAR down the river did he travel, or how far did he swim, all of that will be the hypotenuse. That can also be the “total velocity”

Does the mastery course have simmilar practice problems?

chad i hope to be as knowlegable as you one day you are my king

[@ChadsPrep]

🙂 You can do it!

Was the answer 56 degrees the answer to the question "What was his velocity relative to an observer on shore while crossing?" Or was the answer 3.6 m/s? I was confused. Thank you~
