The discussion , choose three of those problems and explain your approach to solving them. For each selected problem, start by clearly stating the question, then detail your solution either in written form or through a video, ensuring it's at least twenty sentences long.(Il) According to a rule-of-thumb, each five seconds between a lightning flash and the following thunder gives the distance to the flash in miles. (a)Assuming that the flash of light arrives in essentially no time at all, estimate the speed of sound in from this rule. (b) What would be the rule for kilometers?(Il) Every year the Earth travels about 10^9 km as it orbits the Sun. What is Earth's average speed in km/h?(Il) Calculate the average speed and average velocity of a complete round trip in which the outgoing 250 km is covered at 95 km/h, followed by a1.0-h lunch break, and the return 250 km is covered at 55 km/h.
