Answer:
15km/hr
Explanation:
The average speed for the entire trip is the sum of the total distance traveled divided by the total time of the trip.
Total time = 4hr
distance for the first 3hrs = 50km
distance for the last 1hr = 10km
Total distance = 50km + 10km = 60km
Now;
Average speed =
Insert the parameters and solve;
Average speed = = 15km/hr
We have that the magnification of each focal length is given respectively as
A) has
B) has
C) has
From the question we are told that:
Focal Length F
Generally, the equation for Magnification is mathematically given by
Therefore
For A
Therefore
Therefore
For B
Therefore
Where
Therefore
For C
Therefore
Therefore
Therefore
Conclusion
From the calculations above we can rightly say that the magnifications of the values above are
A has
B has
C has
