Question

a sailboat is traveling north at 10 km/h relative to the water. the water is flowing north at 5km/hr what is the velocity of the boat relative to ground

Answer 1

let v=the velocity of the boat relative to the ground

let x=the distance covered on the ground by the boat during time t

let vb= the velocity of the boat relative to the water

let vr=the velocity of the water.

then

v=x/t

and v= the velocity of the boat and the water, since they are both in the same direction.

So v=vb+vr

and the distance covered relative to the ground would be:

x=(vb+vr)*t

Hope this helps

Answer 2

Answer:

Explanation:

let v=the velocity of the boat relative to the ground

 

let x=the distance covered on the ground by the boat during time t

 

let vb= the velocity of the boat relative to the water

 

let vr=the velocity of the water.

 

then

 

v=x/t

 

and v= the velocity of the boat and the water, since they are both in the same direction.

 

So v=vb+vr

 

and the distance covered relative to the ground would be:

 

x=(vb+vr)*t
