For question 1, your work is correct.
For question 2, some information is missing, what is the angle of elevation?
Ques 1:
A box of nuts cost 44 cents per pound. There are 2,600 pieces in a 100 pound box. How much does it cost for 1,960 nuts?
I divided 100 into 2,600 which gave me 26 pieces per #
Then I divided 26 into 1,960 which is 75.38# for 1,960
Then I took .44 X 75.38 and got $33.1672, rounded off to $33.17
Ques 2:
An Airplane goes 500 miles in 1 minute. How long does it take to get to 33,000 feet?
The answer I came up with this is 6.6 minutes
Did I figure these out correctly? Your help with this would be greatly appreciated.
Thanks, in advance

1. typical speed speeds of airliners are ~500 miles per hour, this speed isOriginally Posted by ThePerfectHacker
60 times that, which is faster than the speed needed for orbit (so is probably
greater than a shuttle reentry speed).
2. Lets assume that the climb rate is 500 ft/min. Then the time to 33000ft
is:
.
Dimensionaly (with a slight abuse of dimensional analysis notation) this is:
