Bob heads out into a lake at an angle of 47 degrees with respect to the shore. If his boat is capable of a speed of 2.9 m/s how far from the land will he be in 3 min. and 24 sec.? Answer in units of m.

his movement relative to the shore is 2.9*sin49 m/s
distance= relative velocity*time
be certain to change time to seconds. 
I am confused about where the 49 came from... is it supposed to be 47 ?

yes, 47

Thanks!
