Answer:
800 ft
2/3 minutes = 2/3 min * 60 sec/min = 40 sec
5 ft/sec * 40 sec = 800 ft
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,83,89,97
those are the prime numbers
let cp be x
mp= x+ (20% 0f x)= 1.2x
sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x
profit = 40
sp-cp =40
1.02x-x=40
x=2000
cp =2000
mp= 1.2*2000=2400
