Question 3 1 pts A 246-m-wide river flows due east at a uniform speed of 1.7 m/s. A boat with speed of 7.9 m/s relative to th

Answer 1

Answer #1

Here, for the boat's velocity across the river

component of velocity across the river = 7.9 * cos(34.9 degree)

width of river = 246 m

time taken to cross river = width of river/component of velocity

time taken to cross river = 246/(7.9 * cos(34.9 degree))

time taken to cross river = 38 s

the time taken to cross river is 38 s
