Answer:
66 ⅔ m
Step-by-step explanation:
2 ⅓ km can be written in improper form as 5/3 km.
There's 1000 m in 1 km, so we can convert this:
5/3 km × (1000 m / km) = 5000/3 m
The submarine rises at 800 m/h. So after 2 hours:
distance = rate × time
d = 800 m/h × 2 h
d = 1600 m
So the new position is:
5000/3 m − 1600 m
5000/3 m − 4800/3 m
200/3 m
66 ⅔ m
