The answer is 112 im pretty sure!
Answer: 321 for #1 and 52 for #2
Step-by-step explanation: I divided and got 321 for #1 and 52 for #2.
50,000 = 5 · 10,000 = 5 · 10⁴
To find how many miles per hour you need to divide 50 by 5 to get the number of miles per hour and do the same thing to the 2nd step and to find the difference you need to subtract the numbers. Hope it helps!!!
