What is the average velocity if you drive a distance of 472.5 km at a speed of 40 km/h, then the same distance at a speed of 65 km/h? Answer in units of km/h.
t = d / v
The Attempt at a Solution
11.8125 = 472.5 / 40
7.269230769 = 472.5 / 65
Not really sure where to go from here.
I've done a few of these equations before, Im just having a brain block and I need to submit the answer to this problem by tonight.
Someone just point me in the right direction. :P
