Answer 1

I think that it’s B

Answer 2

Answer:

A penny/coin is 0.75 inches in diameter.

A.

When 288.7 billion pennies are lined up they will form $288.7\times0.75$ = 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 $3600\times24=86400$ seconds in 1 day.

So, 30 million pennies are made in 86400 seconds.

In 1 second, $\frac{30000000}{86400}$=347.22 rounded to 347 pennies per second.

Now assuming 365 days in a year, this becomes $30million\times365=10950million$
