Answer:
C)10.2
Step-by-step explanation:
A is not the correct answer because it is way less than 10.2 and 10.3.
B is not correct because although it has 10, the numbers behind the points are in the ten thousandths place, being less than 10.2.
Then, D is incorrect because it is bigger than the range between 10.2 and 10.3

Solution in the attachment.

Answer:
60 kilometers per hour (kmph) over the limit
Step-by-step explanation:
The speed limit is 60 kmph
Let's find his original rate:
We know D = RT
Where
D is the distance, in km
R is the rate, in kmph
T is the time in hours
He went 10 km in 5 minutes, so we need the time in hours, first. That would be:
5/60 = 1/12 hour
So, putting into formula, we find rate:
D = RT
10 = R(1/12)
R = 10/(1/12)
R = 10 * 12
R = 120 kmph
He was going over by:
120 - 60 = 60 kmph
This is after graphing the equation.
