Unit rates is the rate of a quantity in comparison to 1 i.e. unit.
Based on the given parameters, Shanya is the fastest typist
From the question, the unit rates are given as:
- James: 0.5 words per second
- Shanya = 3 words per seconds
The unit rates of Tristan and Ebony are not given.
So, we compare the rates of James and Shanya
3 words in a second is greater than 0.5 words in a second.
Hence, Shanya is the fastest typist

The speed v is 12 m/s.
You need to convert the seconds to hours and meters to kilometers:
3600s = 1 hr
If you divide 3600 on both sides you will get
1 s = (1/3600) hr
1000m = 1 km
If you divide 1000 on both sides you will also get
1 m = (1/1000) km
v = [(12/1000) km] / [(1/3600) hr]
v = [(12*3600)/1000] km/hr
v = 216/5 km/hr
The distance in 4 hours is
d = [(216/5) km/hr] * 4hr
d = 864.50 km
This is why your answer should be 12 m/s

Answer:
x = 2 and y = 3
Step-by-step explanation:
For us to have a parallelogram, the opposite sides must be equal in length
Thus, we have it that;
2y + 2 = y + 5
2y - y = 5-2
y = 3
To get the value of x
y + 4 = 2x + 3
Recall y = 3: substitute this value
3 + 4 = 2x + 3
3+ 4 - 3 = 2x
2x = 4
x = 4/2
x = 2
