It is estimated that a driver takes, on average, 1.5 seconds from seeing an obstacle to reacting by sound of lightning (thunder) travels at the speed of sound, which is about 750 miles per hour. 1. If you see a flash of lightning, then hear the thunder 4 seconds later, how far away is the lightning? 2. Now let’s generalize that result. Suppose it takes n seconds to hear the thunder after a flash of lightning. How far away is the lightning, in terms of n?

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

answer: 193

explanation:

200-7 = 193

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
