Question 20 (1 point) A boat is sailing with a velocity of
40k(m)/(h)[S] relative to the water, while the water current flows at a velocity of
65k(m)/(h)[W70 S ] relative to the ground. What is the velocity of the boat relative to the ground?
103k(m)/(h)[W78\deg S]
76k(m)/(h)[W70\deg S]
31k(m)/(h)[W43
{[
:3\deg s]}
