Answer is 4,400,000 kg • m/s
11.46 meters
55 km/h = ? m/s
55 km/h × 1000 (meters per km) = 55,000 m/h
55,000 m/h ÷ 3,600 (seconds in an hour) = 15.28 m/s
15.28 m/s × 0.75 s = 11.46 m
Explanation:
Pure substances are typically elements and compound with the following characteristics:
- Pure substances are distinct substances.
- They are homogeneous in all their parts i.e they are the same all through.
- They have a definite composition
- They cannot easily be separated or broken down into simpler substances by physical means.
- Separation by physical means is not easy
- They have a unique sets of physical properties
Impure substances are mixtures. They have the following features:
- Their composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass.
- Constituents retain their identities i.e physical properties are retained.
- The constituents reacts differently to changed conditions.
- They can easily be separated into their constituents by physical methods.

For the answer to the question above,
the distance from i to j is 5 parts
(2 parts from i to k and 3 parts from k to j)
The y distance from i to j is
10 - 2 = 8
Each part is 8/5 = 1.6
Therefore the distance between the 2 parts from i to k is 3.2
From the y coordinate of I which is 2 plus the 3.2 to point k
2 + 3.2 = 5.2
Answer y =5.2
Now just convert that to fraction and that will be the answer
