Problem
A bus moves along a straight highway in two stages.
(i) In the first stage it covers 40km in 1h.
(ii) In the second stage it covers an additional 60km in 2h.
Answer the following:
(a) Calculate the total distance travelled and the total time taken.
(b) Determine the average speed of the bus for the entire journey.
(c) If the bus had maintained a single uniform speed to cover the same 100km in the same total time, what would that uniform speed have been?
(d) Draw a distance–time graph for the complete motion, marking clearly the two stages and the key numerical values.
