The solar system moves at the speed of 828,000 km/h. tara writes the following steps to calculate this speed in decameters/second (dm/s). [1 km = 100 dm] step 1: divide 828,000 by 100. step 2: divide the result obtained in step 1 by 60. step 3: divide the result obtained in step 2 by 60. step 4: write the number obtained in step 3 with the unit dm/s. which step is incorrect in the conversion?
