An object travels in a straight line at a uniform velocity of 10 m/s for 3 seconds and then travels for 2 seconds at a constant speed of 5 meters per second in the same direction. Calculate the total distance traveled.
As I said in the other thread where you asked the same question, you only need one formula. If I tell you what it looks like I will have done too much already. We're supposed to offer hints here, not complete solutions.
