1. Starter 1 (1-D) A car travels 100 km from city A to city B. If the first half of the distance is driven at 50 km/h and the second half is driven at 100 km/h, what is the average speed of the car? How would this change if the car spent equal amounts of time at 50 km/h and 100 km/h ? (select any time interval)

3. Pg 47 #5 Does knowing the distance between two objects give you enough information to locate objects? No, because a single distance could correspond to a variety of different positions of the objects.

4. Pg. 47 #6 A) Bear B has the greater avg. velocity B) Bear A has the greater velocity at t = 8.0 min. C) No. The velocity of Bear A has a positive velocity from 0 to 40 s, a negative velocity from 40-50 s, and a positive velocity from 50 to 60 s. D) No, the velocity for Bear B is never negative.
