He has learned that there is a new space shuttle under development that can travel at a speed of 28,000 kilometers per hour. Brayden is trying to determine how long in days it would take a space crew on this new shuttle to reach Pluto. His work is below. Note: 1 day = 24 hours. Step 1: Distance = RatexTime Step 2: time=dis tan ce rate 5.9x10° 2.8x104 Step 3: time = Step 4: time = 2.11 x 1013 hours 2.11x 103 hours I day 24 hours Step 5: time = 1 Step 6: time = 8.792 x 10" days Part A: Identify the step where Brayden made his error and explain what he did wrong.
