The correct answer is b) The rate of change of the cost of the taxi ride is $2.00 per minute.


This is proven with simple mathematics of how to calculate the fare of a taxi ride.
Interestingly these simple equations are also used to measure the fare in a black taxi cab of London and even those for your Uber car.
