A river is flowing due east at 5 mi/h. A man heads his motorboat in the direction N 30° E in the river. The speed of the motorboat relative to the water is 7 mi/h. (Let east-west be represented by the first component, and north-south be represented by the second component.) (a) Express the true velocity of the motorboat as a vector. (b) Find the true speed and direction of the motorboat. (Round your answers to one decimal place.)
