Answer: The average speed over the entire trip is 3.94 m/s
Explanation:
As we know : 
Let the distance of straight line from point to point be = d
Total distance covered = 2d
Time taken to cover the forward journey = 
Time taken to cover the backward journey = 
Total time for the journey = Time taken to cover the forward journey + Time taken to cover the backward journey = 
Average speed = 
Thus average speed over the entire trip is 3.94 m/s
The power dissipated by a resistor is equal to

where R is the value of the resistance and I is the current flowing through the resistor. From the formula, we can see that the larger R, the larger the dissipated power, so the greatest resistance dissipates more power.
Answer:
you have patience the distance.
