An inverse variation function has the following form:
where is constant.
Because the function traverses (4, 5). therefore
5
As a result, the required function is
or
Check that the function is correct by passing it through the point (10, 2).
When x = 10, get
This confirms that the function is correct.
Answer:
I hope this helps.
Speed = Distance / Time, therefore, Speed = 827km / 10.55 hrs. I got 10.55 hours because I converted the 33 minutes into hours and got 0.55 and added it to the 10 hours which is given. so the answer would be approx. 78.39 km / h. I rounded it to the nearest 2 decimal places.

To help use the Rule GEMDAS
G=Grouping
E=Exponents
M=Multiply
D=Divide
A=Addition
S=Subtract
When you add something, you gain more of it. Therefore, it should be positive 2
