If a migrating hawk travels m mph in still air, what is its rate when it flies into a steady headwind of 3 3 mph? what is its rate with a tailwind of 6 6 mph

Headwind of 4 mph: m-4

(Since the headwind is going against the hawk, the hawk should be slower. You subtract 4 from the speed, which in this case is the variable M)

Tailwind of 6 mph: m+6

(Since the tailwind is going with the hawk, the hawk should be faster. You add 6 to the speed, which is in this case is the variable M)
