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 ...
We will be using the formula d = vt extensively in these problems. Let’s build a chart. The goal is to have TWO, not three or more, variables present in the chart. The formula d = vt has three variables, and since the speed, distance, and time can be different for each train, theoretically we could have six variables.
Question 1: Calculate the average speeds for each of the following, without using a calculator. (a) A car travels 60 miles in 2 hours (b) A lorry travels 120 miles in 3 hours
Speed is the distance you are travelling, divided by the length of time that it takes you to get there. Speed = Similarly, we can rearrange this equation as. Distance = Speed x Time . and . Time = Example. This chart describes the distance between four towns.
This formula shows that: Speed increases if you cover more distance in the same amount of time, or if you cover a distance in less time. Distance can be calculated if you know the speed and time, with the formula: distance = speed × time.
When solving distance problems we will use the relationship rt = d or rate (speed) times time equals distance. For example, if a person were to travel 30 mph for 4 hours. To find the total distance we would multiply rate times time or (30)(4) = 120. This person travel a distance of 120 miles.
