9. A bicycle is to travel on a track with a length of 12 km. (a) The bicycle travels half of the total length at 10 km/h and the other half of the length at 30 km/h. (The transition fron one speed to the other is instantaneous (i.e., the velocity-versus-time graph is discontinuous at that transition point).) Determine the bicycle's average speed and its total travel time. (b) Instead, the bicycle travels this length at 10 km/h during half of...

A trucking company pays drivers an hourly wage to drive trailer-loads of cargo to destinations. A fully-loaded tractor-trailer rig itself also costs the company an average of $1.25/mile to operate (for fuel, maintenance, insurance, etc.). distant To monitor the safety and whereabouts of drivers and cargo, each truck is equipped with a GPS tracker, which transmits a continuous (second-by-second) record of the truck's position; and a speedometer recorder, which transmits a continuous record of its speed (in mph). And the...
