Answer:
12 hours
Step-by-step explanation:
It would be 12 hours for the plane to go from a city to another/the other city
(Distance=speed x time, Speed =distance ÷ time and Time =distance ÷ speed)
If you would apply the formula for time then
7,200m ÷ 600m/h = 12 hours
-2
Its this number because its the number right outside of the ()
105
Let the angle of B be x
According to the question,
5x+x=90
or, 6x=90
or, x=15
The angle of B is 15
The angle of A is (15*5)=75
The supplementary angle of A is
(180-75)=105
The answer is swim city, work is shown in the pic :D
