Speed & Distance-Time Graphs
Calculate average speed using the equation speed = distance ÷ time, represent journeys on distance-time graphs, and interpret gradient as speed and flat sections as stationary periods

Question 1 of 3
A distance–time graph for a runner shows a straight line from (0 h, 0 km) to (4 h, 80 km), a horizontal line from (4 h, 80 km) to (5 h, 80 km), and then a straight line from (5 h, 80 km) to (7 h, 200 km). What is the runner’s average speed for the entire 7‑hour period?
Question 2 of 3
A train travels 240 km in 4 hours. What is its average speed?
Question 3 of 3
A distance‑time graph shows that a car is at 0 m at time 0 s, at 20 m at time 4 s, remains at 20 m at time 8 s, and reaches 40 m at time 12 s. What is the car’s average speed during the interval from 4 s to 12 s?
