After an explosion of an oxygen tank, three astronauts were
forced to move into the lunar lander that was attached to
their spacecraft.
If the lunar lander had enough oxygen to last 2 people for 6
days, is there enough oxygen for 3 astronauts if their
journey back to earth will take 4 days?
Yes, there is enough oxygen for 3 astronauts to journey
back in 4 days.
If the lunar lander had enough oxygen to last 2 people for 6
days, is there enough oxygen for 3 astronauts if their
journey back to earth will take 4 days?
Why or why not?
______________________________________________
If there is 1 unit of oxygen for each person, there must be 2
units for each of 6 days, which is 12 units of oxygen. 3
people will use 3 units of oxygen in 4 days because there is
still 12 units of oxygen to share.
2 x 6 = 12, and 3 x 4 =12
Why or why not?
