Tail winds push the plane along much faster. A plane traveling at the rate of 300 miles per
hour and having a tail wind of 40 miles per
hour actually makes a speed of 340 miles per
hour.
Ilow far is it from Newfoundland to Iceland,
if the trip was made in 4 hours and the plane
had an average speed of 500 miles per hour
with a tail wind of 30 miles per hour?
