Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 6 - No. 34)
A car travels 60 km in 1 hour. Then, in a second hour, the car travels 0 km. What is the speed-time graph for this scenario?
A horizontal line followed by a straight line downwards
A horizontal line followed by a horizontal line
A straight line upwards, then a straight line downwards
A straight line upwards, then a horizontal line.
Explanation
The car has a speed of 60km/hr for the first hour then it stops, so, speed is 0 for the second hour. The graph is flat in both instances.
