Answer:
198 km
Step-by-step explanation:
The speed of the boat supposed to be x km/h
(x+2)*9 = (x-2)*11
9x + 18 = 11x – 22
2x = 40
X = 20
Distance between 2 places: (20 + 2) * 9 = 198 km
Or (20 – 2 ) * 11 = 198 km
Answer:
just graph 5 like usual.....
Step-by-step explanation:
First, change the measurements of the pole to m so all of the units are the same.
41 cm=.41 m
72 cm=.72 m
Then, let x represent the height of the building
30/x=.72/.41
x=30*.72/.41
x=52.68 m
round to 52.7 m
