The rule of a geometric sequence:
We have:
Find 
substitute:
Like
you said: 10 beats per minute, which is 20% percent of its normal value.
So:
10 per minute is 20% of the normal rate. You will divide each side by 0.2, which
will result in 50 per min

I got 0.3125 (i don’t know if that’s correct, because the question was hard for me to understand)
I think this problem gave the data for the radius of earth so that we will know the conversion ratio between statute miles and nautical miles. However, you can simply search that. There are 1.15 statute miles in 1 nautical mile. Hence,
Distance in nautical miles = <span>884884 statute miles * 1 nautical mile/1.15 statute miles
<em>Distance =769,464.35 nautical miles</em></span>
