A car is traveling with a constant speed 80 miles per hour a road that makes half a circle. What is the average velocity of the car?

Is it: 80(pi/2)=125.6? or should I use the formula: Äd/Ät= 80/(pi/2)=50.95?

  1. During the time required to travel half a circle, the car moved a distance pi D/2 along the road, but advances only a distance D from its trarting position. Therefore the velocity is 2/pi times the speed during that time interval. The velocity would be 50.93 mph
