Answer:
The train takes 8 hours and 52 minutes.
Step-by-step explanation:
Both Zurich and Vienna are in the same time zone, so there is no time to adjust the time zone.
Leaves: 22:40
Arrives: 7:32
From 23 to 7:32 there are (7 - 0) + (24 - 23) = 8 hours.
32 + (60 - 40) = 32 + 20 = 52 minutes.
The train takes 8 hours and 52 minutes.

Answer:
779.4 square units
Step-by-step explanation:
You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.
One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...
A = (1/2)r²sin(α)
Since there are n such triangles, the area of the n-gon is ...
A = (n/2)r²sin(360°/n)
__
For a hexagon (n=6) with radius 10√3, the area is ...
A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units
75 km divided by 5 litres = 14 km
I hope this is right.
