To pass it to atmospheres per kilometer you must multiply the value you have by 1000 because one kilometer represents 1000 meters. Therefore the correct answer would be that 0.992 atmospheres (atm) per meter (m) are 992 atmospheres per kilometer.

Essa pergunta nao esta em forma ingles, então pessoas nao vao entender.
Let p = number of pennies.
Let n = number of nickels.
We are given that n= 2p and the total value is $8.80.
We know that a penny = $0.01 and that a nickel = $0.05.
So $0.01p + $0.05n = $8.80.
Substitute 2p for n:
$0.01p + $0.05*2p = $8.80
$0.01p + $0.10p = $8.80
$0.11p = $8.80
p = 80
So n = 2p = 2*80 = 160
Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.
