An airplane is flying at 400 miles per hour due west The wind is blowing from due north at 30 miles per hour what is the speed and direction of the plane?
First part of the question is 400 miles per hour
Is 28 miles per hr is faster then 19 knots per hr?
No. The two units are not comparable. Miles per hour is a speed. Knots per hour is an acceleration. However, I think the question was wrongly phrased and by knots per hour the question actually meant just knots (nautical miles per hour.) A nautical mile is longer than a mile: 1 nautical mile = ~1.15 miles. So 19 knots = 1.15 * 19 miles per hour = 21.85 mph. The answer is: Yes (if by knots/hr the question really meant knots) or No (if the question was initially correctly phrased.)
How long will it take to travel 850 miles an hour at 65 miles per hour?
You must make a formula and convert the units to solve this problem. 65 miles per hour is a speed. 850 miles is a length. If you are travelling at 65 miles per hour, then you will have traveled 65 for every hour. At this point, it becomes a simple division problem. 850 miles covered at 65 miles per hour is 850 miles/65 miles/hour. 850/65 = ~13. The miles on the top and bottom of the fraction cancel out, and you are left with hours. So the time taken will be ~13 hours.
Convert 176 feet second to miles hour?
Assuming the question is refering to feet PER second and miles PER hour, 176 fps = 120 mph
How many miles per hour is 1km?
1 km is a measure of distance, not speed. On the other hand, miles per hour is a measure of speed not distance. So there is a basic fault in the question.1 km = 0.621 milesand 1 km PER HOUR = 0.621 miles per hour
