I want to know the answer to the following question:
How much faster do Red knots and dunlins fly in a flock?
All the background I'm provided with is that "Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (3.1 mph) faster in flocks than when they were flying alone.". Is that enough to answer the question?
