Ch3_2 #1

See Ch 3 Sheet 13,14,14'. You have to modify the equation on sheet 14' such, that the velocities, added with the appropriate relative sign , and the travel time give the travel distance. You do this twice, for the trip down the river, then the return. You obtain 2 equations with 2 unknowns, the velocity of the boat relative to the water (Vbw: Part B) and the velocity of the water relative to ground (Vwg: Part A). The latter is being asked for. Watch out for the relative sign of the velocities on the trip up the river! You solve the 2 equations for the 2 unknowns by substitution.
