The distance traveled by the certain object is the product of its speed and the time it traveled. Mathematically,
D = st
where s is the speed,and t is the time. Substituting the known values,
D = 12(x)
where x is the time in minutes.
D = 18(x - 15)
Equating the terms,
12(x) = 18(x - 15)
The value of x from the equation is 45 minutes or 0.75 hour.
D = (12 km/h)(0.75 h)
D = 9 km
Answer: 9 km
12 x 80 = 960
18 x 86 = 1548
960 + 1548 = 2508
12 + 18 = 30
2508/30 = 83.6
The class average is 83.6
Answer:Passage: Also, he gives the impression that it was only he who really climbed it on his own, and that he then practically pulled me, so that I “finally collapsed exhausted at the top, like a giant fish when it has just been hauled from the sea after a terrible struggle.” Since then I have heard plenty about that “fish,” and I admit I do not like it.

The sentence describing the scale of the model is 1 m represents 40m.
Given,
The length of the ship = 120 m
A scale model of the ship is made.
The length of the model = 3 m
We have to find that, 1m in model represents how much meter of the original.
Scale model;
A physical model that is geometrically similar to an object is called a scale model (known as the prototype). Scale models may be larger than small prototypes like anatomical structures or subatomic particles, but they are often smaller than huge prototypes like cars, buildings, or people.
Here,
Original ; scale model
120 ; 3
That is,
120/3 = 40
Therefore,
1 meter in scale model represents 40 m of the original ship.
