A researcher was observing traffic along one lane of a rural highway. During a 1 minute time interval, ten vehicles were observed travelling 65, 64, 71, 66, 58, 72, 69, 66, 55 and 62 mph. Using these spot speeds, calculate the time mean speed (mph). Provide your answer to the nearest tenth of a mph.

A researcher was observing traffic along one lane of a rural highway. During a 1 minute time interval, ten vehicles were observed travelling 65, 64, 71, 66, 58, 72, 69, 66, 55 and 62 mph.

![The formula shown in the image represents the calculation of the Time Mean Speed (TMS) in traffic flow analysis. It is expressed as follows:
\[ S_{TMS} = \frac{1}{n} \sum_{i=1}^{n} \text{spotspeed}_{i} \]
Where:
- \( S_{TMS} \) is the Time Mean Speed.
- \( n \) is the number of observations or vehicles.
- \(\text{spotspeed}_{i}\) is the individual speed of each vehicle observed.
This formula calculates the average speed of vehicles measured over a specific point or location in traffic, often used in traffic engineering to analyze flow and speed distributions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F10c04a6c-d2d1-4239-bbc7-1827930caaec%2Fcab1a203-3172-4bdf-8c1d-e3e3aae36f2e%2Fggbak5d_processed.png&w=3840&q=75)
