Answer:
2.20752 x
Step-by-step explanation:
The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.
365 days refer to the total number of days per year86,400 seconds refer to the number of seconds per dayLet's solve.
365 x 86,400 = 31,536,000 or 3.1536 x <em>Therefore, one year has 3.1536 x </em> <em> seconds. </em>
Next, you have to know the number of seconds in 10 billion years.
(3.1536 x ) x (1.0 x ) = 3.1536 x The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.
(3.1536 x ) x 7,000,000 = 2.20752 x
