Question

At noon, ship A is 40 nautical miles due west of ship B. Ship A
is sailing west at 25 knots and ship B is sailing north at 20
knots. How fast (in knots) is the distance between the ships
changing at 4 PM? (Note: 1 knot is a speed of 1 nautical mile per
hour.)

Note: Draw yourself a diagram which shows where the ships are at noon and where they are "some time" later on. You will need to use geometry to work out a formula which tells you how far apart the ships are at time t, and you will need to use "distance = velocity * time" to work out how far the ships have travelled after time t.

Answer #1

At noon, ship A is 10 nautical miles due west of ship B. Ship A
is sailing west at 25 knots and ship B is sailing north at 23
knots. How fast (in knots) is the distance between the ships
changing at 6 PM? (Note: 1 knot is a speed of 1 nautical mile per
hour.)
What is the answer in knots? Please neat answers only!

At noon, ship A is 30 nautical miles due west of ship B. Ship A
is sailing west at 24 knots and ship B is sailing north at 18

At noon, the Titanic is 1414 nautical miles due west of
the SS Minnow. The Titanic is sailing west at 2020 knots and the SS
Minnow is sailing north at 2525 knots. How fast (in knots) is the
distance between the ships changing at 33 PM? If necessary, round
your answer to at least three decimal places.
(Note: 1 knot is a speed of 1 nautical mile per hour.)

At noon, ship A is 120 km west of ship B. Ship A is sailing
east at 20 km/h and ship B is sailing north at 15 km/h. How fast is
the distance between the ships changing at 4:00 PM?
km/h

At noon, ship A is 50 km west of ship B. Ship A is sailing south
at 20 km/h and ship B is sailing north at 10 km/h. How fast is the
distance between the ships changing at 4:00 PM? (Round your answer
to one decimal place.)

3. (5pts) At noon, ship A is 120km west of ship B. Ship A is
sailing north at 35km/h and Ship B is sailing south at 25km/h. How
fast is the distance between the ships changing at 4:00pm

(A)At noon, ship A is 140 km west of ship B. Ship A is sailing
east at 25 km/h and ship B is sailing north at 20 km/h. How fast is
the distance between the ships changing at 4:00 PM?
(b) If a snowball melts so that its surface area decreases at a
rate of 5 cm2/min, find the rate at which the diameter
decreases when the diameter is 9 cm.

At noon, ship A is 20 miles west of ship B. Ship A is traveling
due east at an average speed of 4mph, at the same time ship B
travels south at an average speed of 5mph. How fast is the distance
between ship A and B changing at 2:00pm?

A cruise ship maintains a speed of 16 knots (nautical miles
per hour) sailing from San Juan to Barbados, a distance of 600
nautical miles. To avoid a tropical storm, the captain heads out
of San Juan at a direction of 10 degrees off a direct heading to
Barbados. The captain maintains the 16 dash knot speed for 7
hours, after which time the path to Barbados becomes clear of
storms. (a) Through what angle should the captain turn to...
