Homework Help: Calculus

Posted by Jessica on Monday, March 5, 2012 at 2:36pm.

The fuel efficiency, E, in litres per 100 km, for a car driven at speed v, in km/h is E(v)=1600v/(v^2+6400)

a)If the speed limit is 50 km/h, determine the legal speed that will maximize the fuel efficiency.

Could someone explain to me why the legal speed is 50 km/h to maximize the fuel efficiency with calculations and explanations? My teacher it cannot be 50.
