1) A car drives to the east in a time of 5 hours. Then, immediately (not realistic, but just assume this is the case for this problem), travels 14 km to the west in 3 hours. The average speed for the entire trip is 6 km/hr. What is the average speed of the car for the first part of the trip, in km/hr, while the car was traveling east?

2] A car drives to the west with a magnitude of the average velocity of 25 km/hr for 4 hours. Then, immediately (not realistic, but just assume this is the case for this problem), travels to the east for 3 hours. The average velocity for the entire trip is 3 km/hr to the west. What is the average velocity of the car for the second part of the trip, in km/hr, while the car was traveling east? If to the west (-x direction), include a negative sign.
