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 ...
It includes: 1) A calculation of speed using the formula speed = distance/time, finding a speed of 20 m/s. 2) A calculation of time by subtracting two time values, finding a time of 20 seconds. 3) Another calculation of speed using the formula speed = distance/time, finding a speed of 10 m/s.
This document provides formulas and examples related to time, speed, and distance. It includes 8 formulas covering topics like: 1) The relationship between distance, speed, and time 2) Average speed when a journey is divided into different parts 3) Relative speed when objects are moving in the same or opposite directions 4) Calculating stoppage ...
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.
The document discusses distance-time graphs and how to calculate speed, distance, and time from the graphs. It provides examples of distance-time graphs with questions to calculate the fastest part of a journey, time spent parked, and speed during different sections.
