Courtney takes 2.4 x 10 to the 4th power steps during her long distance run each step covers an average of 810 mm what's the distance and then it is that going to cover during her run and scientific notation then convert the distance to the appropriate unit kilometers write answer in standard form

The total distance covered is the number of steps multiplied by the average distance for each step. distance = (2.4 x 10^4) (0.810 m) distance = 1.944 x 10^4 meters We can convert this distance in meters to units of kilometers by dividing by 1000. distance = (1.944 x 10^4 meters) / (1000 m/km) distance = 1.944 x 10^1 kilometers distance = 19.44 kilometers The total distance covered during the run is 1.944 x 10^4 meters which is equal to 19.44 kilometers.
