Hello.
2 Quick Questions - Would be grateful for some help.
1) When calculating the average speed of a car, if the car stops for 10 minutes, do you take the 10 minutes into account when calculating average speed?
2) My weak spot is Geometry. When is the best place to find GMAT questions solely focused on Geometry?

kusum, 1) Yes, you take 10 minutes into account if you are calculating average speed for overall trip. The average speed equals to total distance divided by total time. Just be attentive to what part of a trip you are asked about.
