Assuming that you meant she drives 129 km everyday (her work hours are not stated) then the answer should be 3999km.
To find this, simply multiply her daily kilometers (129) by the days (31) in order to find how many she drives in the set period of time provided.
Hope this helps!

Answer:
True
Step-by-step explanation:
Answer:
100 J
Step-by-step explanation:
The formula for kinetic energy is as follows:

where
KE= kinetic energy (J)
m= mass (kg)
v= velocity (m/s)
Given: m= 50 kg, v= 2 m/s
Substituting the given information into the formula:
KE
= ½(50)(2²)
= ½(50)(4)
= 100 J
First, you need to make the fractions have the same denominator:
15 1/2 ---> 15 + (1/2 x 5) = 15 5/10
2 1/10 ---> 2 1/10
Then you need to subtract them from each other:
15 5/10
<u>- 2 1/10</u> (or) 15 5/10 - 2 1/10 = 13 4/10
13 4/10
This gets the answer: <u>13 4/10</u>
