Question

the distance between two ships

Answer 1

with the set up you gave me i got 3600? idk if thats correct?

Answer 2

Take the derivative of this with respect to time. Remember the product rule

2*dc/dt = 2*da/dt*a + 2*db/dt*b

a is the distance that the ship traveled in four hours plus the initial 40 knot offset
a = 40+16*4
b is the distance that the ship traveled in four house
b = 17*4

therefore,

dc/dt = (16)*(40+16*4) + (17)*(17*4)

Answer 3

the answer is gave me was 2820

Answer 4

is that correct?

Answer 5

ok

Answer 6

the website that im submitting my answer on is telling me that its incorrect

Answer 7

well drawing a diagram is always a good start



you need to find the hypotenuse of C

the side for ship A is a = 16 x 4 + 40

the side for ship B is b = 17 x 4

calculate those 1st then use pythagoras' theorem to find c

hope it makes sense
