Q. At noon, ship A is 200 km east of ship B and ship A is sailing north at 30 km/h. Ten minutes later, ship B starts to sail south at 35 km/h.
a. What is the distance between the two ships at 3 pm?
b. How fast (in km/h) are the ships moving apart at 3 pm?
Car A is moving east at 63 kph while Car B is moving in the direction of N 45° E. For a passenger in Car A, B appears to be moving away in a direction of N 30° W. Solve for the velocity, in kph, that B appears to the passengers in A. Round your answer to 2 decimal places.
