Answer: C) a natural resource that humans use to generate energy
So basically its anything found on earth to make energy. This includes nonrenewable sources such as fossil fuels (coal or natural gas), and renewable sources such as wind, hydro or solar.
Given:
Total distance = 1000 kilometer
Total time = 5 hours
To find:
Average speed = ?
Formula used:
=
Where = average speed
s = total distance
t = total time
Solution:
Average speed of the jet is given by,
=
Where = average speed
s = total distance
t = total time
=
= 200 km/ h
Thus, average speed of the jet is 200 km/h.
Hence, Option (A) is correct.

Answer:
0.0083km or 8.3m
Explanation:
Given parameters:
Distance = 5km
Time = 10min
Unknown:
Distance moved in 1sec = ?
Solution:
To solve this problem, let us first find the speed of the motorbike.
Speed =
Speed = = 0.5km/min
So;
In 1sec:
60 sec = 1 min
1 sec = min
Distance moved in 1sec = speed x time
Distance moved = 0.5km/min x min = 0.0083km or 8.3m
