How many trees does it need to absorb the released CO2 in one hour by driving a car also for one hour by average speed of 100 km per hour?

A car has at 100 km/h a CO2 emission of 135 gr/km.
(see link below for reference)
Say it runs for 1 hour it drives 100 km (assume no speed changes) then an amount of 135*100 = 13500 gr or 13,5 kg of CO2 emitted.
A young tree of the Sahel absorbs about 10 kilos of CO2 a year.
(see the link below for reference)
This means that 10/(365*24) = 0.0011 kg/ hour per tree can be taken as a rough estimation.
Therefore the answer to your question would be you need 11,842 trees in order to clear the CO2 within 1 hour.
Keep in mind that CO2 will spread over a very large area, but that it is still a significant amount of trees needed
*Keep in mind that the calculation is done on facts found, and could therefore differ from reality as no scientific study has been done.

Is it possible to have an average speed larger than the top speed?
No, that isn't possible. 'Average speed" indicates the time you need to get from A to B. If you start at point A and accelerate to top speed as quickly as possible, there will always be a period where you are still driving at less than top speed. And if you first accelerate to top speed before reaching point A, the best you can do is driving from A to B at a speed equal to top speed.
