A pilot wishes to fly from Bayfield to Kitchener, a distance of 100 km on a bearing of 105°. The speed of the plane in still air is 240 km/h. A 20 km/h wind is blowing on a bearing of 210°. Remembering that she must fly on a bearing of 105° relative to the ground (ie the resultant must be on that bearing), find the heading she should take to reach her destination how long will the trip take

I would start by adding the velocity vectors here, I think. Can you find the resultant speed?

OpenStudy (anonymous):

Why?

OpenStudy (joannablackwelder):

Hm, hold on. I am still working on it....

OpenStudy (anonymous):

Okay Thanks same here!

OpenStudy (joannablackwelder):

I found the resultant magnitude by law of cosines.

OpenStudy (joannablackwelder):

But I haven't yet found the angle.

OpenStudy (joannablackwelder):

I think I can get it using summing the x components and y components and using trig ratios, but I have to go. Sorry!

OpenStudy (joannablackwelder):

I'll be back on later today.

OpenStudy (joannablackwelder):

You can use rate=distance*time to find time once you have rate.

Okm thx

No worries
