1/2 pounds,
assuming that each friend takes an equal part of the 2 1/2 pounds, then 2 1/2 divided by 5 would get you 1/2 pound
The speed of earth will be found as follows:
speed=distance/time
distance=93 million
time=365
speed=(93)/365=254, 794.5205 mi/day
thus distance moved for 8 days will be:
distance=speed*time
=(254794.5205)×8
=2,038,356.164 miles
Quadrant II.
Hope this helps.
