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

Step-by-step 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`
