23x - 1 = 45
23x = 1 + 45
23x = 46
x = 46 : 23
x = 2
164+56−(3+4+1)
=220−(3+4+1)
=220−(7+1)
=220−8
=212
Answer:
Time = distance/speed. T = 1,200,000,000/28,000. This can be cancelled to 1,200,000/28. Rounding 28 to 30 for the estimate, divide by another ten: 120,000. Then divide by the remaining 3 from 30: 120,000/3 = 40,000. It will take approximately 40,000 hours.
