Kristina’s journey is shown on the distance-time graph below. (a) Work out Kristina’s average speed, in kilometres per hour. (b) Use the information to plot Lucas’s journey on the same distance-time graph.
The distance-time graph shows the speed of the cyclist over a 20km race. He travels at a constant speed for the first 10km and then slows down over the second 10km. a. Calculate the average speed of the cyclist over the whole race. b. Calculate the difference in the speed of the cyclist over the first half and second half of the race.
This lesson unit is intended to help you assess how well students are able to interpret distance–time graphs and, in particular, to help you identify students who: • Interpret distance–time graphs as if they are pictures of situations rather than abstract representations of them. • Have difficulty relating speeds to slopes of these graphs.
(i) A plane travels at a speed of 250 mph and covers a distance of 2250 miles. Question 10: Calculate how long each journey lasts. Give each answer in hours and minutes. (a) A car travels 100 miles at a speed of 40mph. (b) A lorry travels 90 miles at a speed of 60 mph. (c) A bus drives at a speed of 48mph and covers a distance of 60 miles.
How to Find Distance in Speed-Time Graph. The diagram below shows a speed-time graph of a car. A straight line indicates a constant speed for a length of time. In order to calculate distance traveled, you’ll need to consider the horizontal axis and vertical axis as length and breadth.

Categorisation: Determine the exact distance travelled by finding the area under a distance-time graph consisting of straight lines. [Edexcel New SAMs Paper 1H Q21a] Here is a speed-time graph for a car journey. The journey took 100 seconds. The car travelled 1.75 km in the 100 seconds. Work out the value of 𝑉 . 𝑉= ..... m/s
