Answer:
The speed is 
Explanation:
We have the data of the gasoline pumping rate.
The gasoline pumping rate indicates the amount of gasoline per unit of time that the fuel pump sends to the car's fuel tank. We indicate the gasoline pumping rate with 

Its units are
which are units of mass over time
The density of the gasoline is 
The density is equal to 
If we divide the GPR by the density we obtain :

Where
is the volume flow rate (VFR) :

The VFR is equal to area per speed.

The area (A) is equal to
given that the fuel line is circular.
![A=\pi.R^{2}=\pi.[(3.43).10^{-3}m]^{2}=(3.6960).10^{-5}m^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi.R%5E%7B2%7D%3D%5Cpi.%5B%283.43%29.10%5E%7B-3%7Dm%5D%5E%7B2%7D%3D%283.6960%29.10%5E%7B-5%7Dm%5E%7B2%7D)
Now we have the VFR and A. The final step is to calculate the speed (S) :



The speed of the gasoline is
