A car travels along a straight stretch of road. It proceeds for 14 mi at 50 mi/h, then 28.3 mi at 48 mi/h, and finally 37.4 mi at 38.3 mi/h.
What is the carâ€™s average velocity during
the entire trip?
Answer in units of mi/h

avg velocity= totaldistance/totaltime

can u show me the steps to the problem.
thanks
