A car passes through an intersection at 45.0 mi/h and then passes through another intersection at 30.0 mi/h. Determine the average speed of the car in mi/h.

i pretty sure it is

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
