a plane is flying due north at 155 mi/h and encounters a wind from the west at 45m/h. what is the plane's new velocity with respect to the ground in standard position. answer is 128 mi/h at 239.4. how do i get to this answer.

**Trig**

This has to do with vectors...I'm wondering if I set up the diagram correctly? A plane has a speed of 250mph and flies with a bearing of N35degE. The wind is blowing from the west at 25 mph with a heading of due east. What is the actual speed and heading of the plane?

**Math Ms. Sue please help**

Flying to Kampala with a tailwind a plane average 158km/h. On the return trip the plane only averaged 112km/h while flying back into the same wind. Find the speed of the wind and the speed of the plane in still air.

**Math**

a plane flies due north at 300 mi/h for 3 h then due west at 250 mi/h. If x represents the number of hours the plane is flying due west, determine for what values of x the plane will be more than 3700 mi from it's original point.

**Algebra 2**

An airplane flies 1050 km with the wind. In the same amount of time, it can fly 750 km against the wind. The speed of the plane in the still air is 200 km/h. Find the speed of the wind.
