Question 124336: The Cassini spacecraft mission to Saturn will take more than 61/2 years to reach Saturn. During its mission it will have traveled 2 billion miles in 80.5 months. Find the average speed in miles per hour. Convert 80.5 months to hours then use the formula d=rt.

So far I have:
Hours in a month=730.5 * 80.5 mo.=58805.25t
2,000,000,000d
58805.25t
?=r

The Cassini spacecraft mission to Saturn will take more than 61/2 years to reach Saturn. During its mission it will have traveled 2 billion miles in 80.5 months. Find the average speed in miles per hour. Convert 80.5 months to hours then use the formula d=rt.
:
We want of find r so it would be: r = d%2Ft
where d = 2 billion miles and t = 80.5 months (convert to hrs)
:
r = 2000000000%2F%28%2880.5%2A30%2A24%29%29 = 34,506.55625 mph
:
That's using 30 day months, it might be more accurate if we:
:
Convert 80.5 months to years: 80.5/12 = 6.70833 yrs
Multiply that by 365 = 2448.54 days
multiply that by 24 = 58765 hrs
:
t = 2000000000%2F58765 = 34,033.86 mph
