A police cruiser, approaching a right-angled intersection from the north, is chasing a speeding car that has turned the corner and is now moving straight cast. When the cruiser is `0.6` mile north of the intersection and the car is `0.8` mile to the east, the police determine with radar that the distance between them and the car is increasing at 20 mph. If the cruiser is moving at 60 mph at the instant of measurement, what is the speed of the car ?

A police jeep, approaching an orthogonal intersection from the northern direction, is chasing a speeding car that has turned and moving straight east. When the jeep is 0.6 km north of the intersection and the car is 0.8 km to the east. The police deteremine with a radar that the distance between them and the cae is increasing at 20 km/hr. If the jeep is moving at 60 km/hr at the instant of measurement, what is the speed of the car?

Directions for questions 8-10: A police van, approaching a right-angled intersection from north, is chasing a car that has turned the corner and is now moving straight east. When the van is 0.6 km north of the intersection, the car is 0.8 km to the east. At that instant the police determines with the help of the radar that the distance between the car and the van is increasing at a rate of 20 km/ hr. The speed of the police van at that instant (71) is 60 km/ hr. Q8) If s is the distance between the car and the van, r is the position of the car and y is the position of the van at time t, then

Two cars leave an intersection. One car travels North, other travels East. When the car travelling North had gone 24 km, the distance between the cars was 4 km more than three times the distance travelled by the car heading East. Find the distance between two cars at theat time.

A train is moving due east and a car is moving due north with equal speeds. A passenger in the train finds that the car is moving towards
