An airplane flies with a constant speed of 780 miles per hour. How far can it travel in 4 hours?

3136

Explanation:

because you multiply 780 by 4 because if it has a constant speed meaning it will not change speed then you multiply it by 4 because it says in 4 hours ( I hope this helped)

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
