A river flows due south with a speed of 5.00 m/s. A man steers a motorboat across the river; his velocity
relative to the water is 3.70 m/s due east. The river is 770 m wide.

Expert Solution
Step 1: Time taken

C)

Write the expression for the distance covered by the man to reach the opposite bank and substitute the corresponding values to calculate the time taken by the man to cross the river.

table row cell S equals v subscript m divided by w end subscript cross times t end cell row cell 770 text  m end text equals 3.7 text  m/s end text cross times t end cell row cell t equals 208.108 text  s end text end cell row cell t almost equal to 208.1 text  s end text end cell end table
