Homework Statement
An off-roader explores the open desert in her Hummer. First she drives 25 deg west of north with a speed of 6.5 km/h for 15 mins, then due east with a speed of 12 km /h for 7.5 mins. She completes the final leg of her trip in 22 mins. What are the direction and speed of travel on the final leg? (assume her speed is constant on each leg, and that she returns to her starting point at the end of the final leg)
So I know how to do it, but i am having a bit of trouble trying to figure out the diagram...
can you tell me if it's a right angle triangle?
which angles do i use?
thanks =)
