x= 5
The average travel time is simply the mean travel time between the given points
- The average time that it takes for the car to travel the first 0.25m is 2.23s.
- The average time to travel just between 0.25m and 0.50m is 0.9s.
- Given the time taken to travel the second 0.25 m section, the velocity would be 0.28m/s.
<u>(a) The average time to travel the first 0.25m</u>
The time travel in the first 0.25m are: 2.24s, 2.21s and 2.23s.
So, the average time to travel is:



<u>(b) The average time to travel just between 0.25m and 0.50m</u>
The time travel in the 0.50m are: 3.16s, 3.08s and 3.15s.
So, the average time to travel this distance is:



The average time to travel between both distance is the difference between the average time of each distance.
So, we have:


<u>(c) The velocity in the second 0.25m section</u>
The distance and time are:


So, the velocity is:

This gives

Answer:
Only one solution and its x = −20
Step-by-step explanation:
Firstly, multiply the principal P, interest in percentage R and tenure T in years.
For yearly interest, divide the result of P*R*T by 100.
To get the monthly interest, divide the Simple Interest by 12 for 1 year, 24 months for 2 years and so on.
