Question

30. Sailboat is head out to sea (against the waves) at a rate of
23km/h. The ocean current is 17km/h. What is the actual velocity of the sailboat?

Answer 1

Answer:6 km/h

Explanation:

Given

Velocity of Sailboat is $v_1=23\ km/hr$

Velocity of ocean current is $v_2=-17\ km/hr$

negative sign indicated it is opposite of Sailboat

Therefore, velocity of sailboat w.r.t ocean current is

$\Rightarrow v_{12}=v_1-v_2$

$\Rightarrow v_{12}=23-17$

$\Rightarrow v_{12}=6\ km/h$
