Apolice car is located 50 feet to the side of a straight road. a red car is driving along the road in the direction of the police car and is 140 feet up the road from the location of the police car. the police radar reads that the distance between the police car and the red car is decreasing at a rate of 70 feet per second. how fast is the red car actually traveling along the road?

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
