From Canada to South Africa in a C150

“taking 14 hours to cross from St. Johns to Santa Maria in the Azores - a ground speed of about 95 knots”
■■■■ with nothing but water in sight!

Is this a typo or am I not understanding how the wind works / helps
“The weather was perfect with the help of a 20-knot headwind”
How is a headwind helping to get somewhere?
