The time in seconds between seeing lightning and hearing thunder is about five times the storm's distance in miles. write a function to represent the storm's distance f(s) given the time s. how far away is a storm if this time is 15 seconds?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
