A boat takes 2 hours to travel 15 miles upriver against the current. \[\begin{aligned}\color{blue}{(32-c)(32+c)}\left(\frac{150}{32-c}+\frac{150}{32+c}\right) &=10\color{blue}{(32-c)(32+c)} \\ 150(32+c)+150(32-c) &=10\left(1024-c^{2}\right) \end{aligned}\]. What is the rate of the boat in still water and what is the rate of the current? Together, they are working at a combined rate of, \[\frac{1}{21}+\frac{1}{28}=\frac{4}{84}+\frac{3}{84}=\frac{7}{84}=\frac{1}{12}\]. {\(\frac{2}{3}\), \(\frac{8}{3}\)} and {\(\frac{8}{5}\), \(\frac{2}{5}\)}. Now let's think about the rate the boat travels. Every applicant should memorize these and should be on fingertips. Or, What is the hardest exam in the world? We weren't able to detect the audio language on your flashcards. United Kingdom, EC1M 7AD, Leverage Edu Since x, or its reciprocal, is already isolated on the left, simply add the fractions on the right: Problem 10. we need to write our two equations.
