Two straight highways, one running west to east and the other running north to south meet at an intersection. Car A is on the east-west highway 600 metres east of the intersection and is travelling west at 75 km/h. Car B is on the north-south highway 800 metres south of the intersection and is travelling south at 95 km/h. At what rate is the distance between the two cars changing at this moment? Hint: There are 1000 metres in one kilometre. the distance is deceasing at a rate of 15.5 km/h the distance is increasing at a rate of 31 km/h the distance is deceasing at a rate of 31 km/h the distance is increasing at a rate of 24 km/h the distance is deceasing at a rate of 24 km/h

Question
Transcribed Image Text:Two straight highways, one running west to east and the other running north to
south meet at an intersection. Car A is on the east-west highway 600 metres east of
the intersection and is travelling west at 75 km/h. Car B is on the north-south
highway 800 metres south of the intersection and is travelling south at 95 km/h. At
what rate is the distance between the two cars changing at this moment?
Hint: There are 1000 metres in one kilometre.
the distance is deceasing at a rate of 15.5 km/h
the distance is increasing at a rate of 31 km/h
the distance is deceasing at a rate of 31 km/h
the distance is increasing at a rate of 24 km/h
the distance is deceasing at a rate of 24 km/h
