John drives a distance of 90 km to the right at a steady speed of v1=25.00 m/s. then he stops at the gas station for 10 minutes. then it returns and drives back ( to the left) for half an hour to the left at speed of v2 = 20.0 m/s. speed =total distance/total timevelocity=displacement /total time1 km= 1000 m, 1 minute = 60 seconds, 1 hour= 60 minutesa. what is the difference between speed and velocity? b. calculate the total time of his round trip. c. calculate the total distance. d. calculate the total displacement. e. calculate the average speed. f. calculate the average velocity.
