At a particular instant ship A is 100 km west of ship B, ship A is sailing at a speed of 35 km/hr and ship B is sailing north at 25 km/hr. How fast is the distance between the ships changes after 4 hours

Two ships A and B are sailing away from a point O along routes such that angle AOB is always 120^(@) . At a certain instance, OA = 8 KM OB = 6km and the ship A is sailing at the rate of 20 km/hr while the ship B sailing at the rate of 30km/hr while the ship B sailing at the rate of 30 km/hr. Then the distance between A and B is changing at the rate (in km/hr)

Two ships A and B are sailing straight awayfrom a fixed point O along routes such that angleAOB is always 120^@. At a certain instance, 0.4=8 km, OB=6 km and the ship A issailing at the rate of 20 km/hr while the ship B sailing at the rate of 30 km/hr, then thedistance between A and B is changing at therate (in km/hr): (A) 260/sqrt(37) (B) 260/37 (C) 80/37

A ship A which is at distance of 30km to the north of P moves at 15 km/hr and another ship B which is at a distance of 40 km to the east of P moves at 20 km/hr. How fast the distance between the cars changing?

Two ships A and B are 10 km apart on a line running south to north. Ship A farther north is streaming west at 20 km//h and ship B is streaming north at 20 km//h. What is their distance of closest approach and how long do they take to reach it?
