18.2 Calculating Speed, Distance and Time In this section we extend the ideas of speed to calculating distances and times, using the following formulae: Speed = Distance Time Distance =Speed Time× Time = Distance Speed Example 1 Jane drives at an average speed of 45 mph on a journey of 135 miles. How long does the journey take? Solution Time ...
2 wrz 2018 · The travel graph shows her journey. (a) At what time does she arrive at the sports centre? (b) Work out Sonali’s cycling speed in kilometres per hour..... km/h [2] (c) Sonali stays at the sports centre for 45 minutes. She then takes 30 minutes to cycle home. Complete the travel graph. [2]
Distance-time graphs show distance from a fixed point at different times. Distance is on the vertical axis, and time is on the horizontal axis. The gradient of the graph is the speed. A positive gradient represents the object (or person) moving away from the starting point.
DISTANCE-TIME GRAPHS – PRACTICE QUESTIONS 1. Clive drove to an office for a meeting. After the meeting, he drove straight back home. The distance-time graph below shows his journey. (a) How many kilometres away is the office from Clive’s home? (b) How long was the meeting? (c) How long did it take Clive to drive to the meeting? 2. Danny ...
The diagram shows the speed-time graph of a train journey between two stations. The train accelerates for 3 minutes, travels at a constant maximum speed of 40 km/h, then takes. 4 minutes to slow to a stop. Calculate the distance in kilometres between the two stations.
Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.
Speed from a distance-time graph For the red line, the object travels m in seconds. Hence, we can calculate its speed: m/s N.B. The steeper the line, the faster the speed. E.g. 1 Answer these questions based on the distance-time graph above. (a) How long is the object stationary for? (b) Calculate the speed indicated by the purple line.
