Researchers have been studying the trend in British automobile sales over the past few decades, observing significant fluctuations in the market. If the increase in truck market share between the 1930s and 1950s had been maintained across the studied period and beyond, what would the market share of truck sales be in the 2010s?

Automobiles Sold in Great Britain:
- Motorcycle
- Car
- Truck
- Bus

Percentage of each type:
- 1930s: 16%
- 1950s: 0.26%
- 1970s: 36%
- 1990s: 46%
- 2010s: 0.56%, 66%, 76%, 86%, 10%

To determine the market share of truck sales in the 2010s, based on the given information and assuming a linear increase in truck market share from the 1930s to the 2010s, we will work through the following steps:

1. Identify Given Data:
- Truck market share in the 1930s: 16%
- Truck market share in the 1950s: 36%

2. Time Periods:
- 1930s to 1950s: 1950 - 1930 = 20 years
- 1950s to 2010s: 2010 - 1950 = 60 years

3. Calculate the Increase Rate:
- Increase in truck market share from the 1930s to the 1950s: 36% - 16% = 20%
- Rate of increase per year: [tex]\( \frac{20\%}{20 \text{ years}} = 1\% \text{ per year} \)[/tex]

4. Extend the Increase Rate to 2010s:
- Number of years from the 1950s to the 2010s: 60 years
- Total increase from the 1950s to the 2010s: [tex]\( 60 \text{ years} \times 1\% \text{ per year} = 60\% \)[/tex]

5. Calculate Truck Market Share in the 2010s:
- Starting market share in 1950s: 36%
- Adding the increase over the next 60 years: 36% + 60% = 96%

Thus, if the increase in the truck market share between the 1930s and 1950s had been maintained consistently over the years, the market share of truck sales in the 2010s would be 96%.
