Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –

Question

• Baguio City is approximately 240 km from Manila. A bus leaves the station in Manila. Because of heavy traffic, its speed is only 30.0 km/h for the first 2.0 h. After that, it travels at 50 km/h until it reaches Baguio City. It travels at night on its return trip, covering the distance in only 4.0 h. (a) What is its average speed for the round trip? (b) What is its average velocity for the round trip? Express your answers in m/s.
