The test driver drove from Ostrava to Warsaw at an average speed of 66km/h and the journey took him 6 hours. After him, the same route took several other drivers. (Each driver took a different driving time.) Choose the function giving the average speed v of each of these drivers as a function of the total driving time t from Ostrava to Warsaw.
v=396t,  t∈(0;∞)
v=66t,  t∈(0;∞)
v=66t,  t∈(0;∞)
v=t396,  t∈(0;∞)
