DONATEJOINSIGN INASHBOARDCLASSESLIBRARYSUBJECTSO EXPLORE VWhat do you want to learn today?Going over the speed limit can result in fatal accidentsThe time it takes you to get to a destination is based on average velocity, not instantaneousghtsvelocity.While instantaneous speed is the car's speed at a particular instant in time, average speed isa measure of distance traveled over a period of time.For someone who is running 5 minutes late to an appointment that is 30 minutes away at 65mph, he would need to drive at an average speed of 78 mph. This means he would have totravel at a significantly higher velocity if accounting for realistic obstacles such as slowercars and stoplights.Can You Apply It?Using the information provided above, answer the following questions.1. Why is it unrealistic to think you will get to your destination on time if you are running late inthe scenario described above?2. If your average velocity for the first half of a trip is 30 mph and 20 mph for the second half,what is your overall velocity?3. How much faster would someone reach their destination if they increased their averagevelocity from 50 mph to 60 mph on a 30 mile trip?

Real-life situations are different from the theoretical solutions we get in a notebook. Therefore,…

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.
