Answer:
A penny/coin is 0.75 inches in diameter.
A.
When 288.7 billion pennies are lined up they will form [tex]288.7\times0.75[/tex] = 216.525 billion inches.
If you want to convert it to miles, this is 3417376.89 miles as 1 billion inch = 15782.82 miles.
B.
The mint currently makes about 30 million pennies a day.
Now we have 3600 seconds in an hour.
So, we have [tex]3600\times24=86400[/tex] seconds in 1 day.
So, 30 million pennies are made in 86400 seconds.
In 1 second, [tex]\frac{30000000}{86400}[/tex]=347.22 rounded to 347 pennies per second.
Now assuming 365 days in a year, this becomes [tex]30million\times365=10950million[/tex]
