Calculating Resultant Velocity for Two Equal Velocities at Right Angles

[thehatchetmen]

can someone help me with this question:
Calculate the resultant velocity of a pair if 100 km/h velocities at right angles to each other

i don't even understand what the question is asking me

Velocities are represented with vectors, so use http://www.codesampler.com/d3dbook/chapter_02/chapter_02_files/image012.jpg" . However, for different vector orientations, you get different resultant velocities.

k thank you, that helped a lil...would this be the right answer then:

Since both velocities are equal we have to times one of the sides by the square root of 2. Which means that the reluctant velocity is 141.4.
