I did not understand this subject very well. (Average velocity, instantaneous velocity, average acceleration, instantaneous acceleration) And I am trying to understand with this question. Especially I can't get the "instantaneous" formulas in my head and I can't figure out why we did it. I would be happy if you could solve it in an explanatory way. Thanks.
At 10:11 a.m., you pass a speed radar on the freeway. At 10:31 a.m., you pass a second speed radar along the same freeway. If the second radar was located 18 miles from the first radar, and the speed limit along the entire stretch of highway is 70 mph, could you be fined for speeding based on the radar data?Find your average velocity in miles per hour (note: 20 minutes = 1/3 hour) from 10:11 a.m. to 10:31 a.m. Round to 2 decimal places if needed.
