Calculate the average speed between 0 s and 20 s

2 m/s

Explanation:

The following data were obtained from the question:

Distance (D) = 40 m

Time (t) = 20 s.

Average speed =?

Average speed is the total distance travelled divided by the total time taken. Mathematically, it is expressed as:

Average speed = Total distance /Total time

Thus, we can obtain the average speed as follow:

Total Distance (D) = 40 m

Time time (t) = 20 s.

Average speed =?

Average speed = Total distance /Total time

Average spee= 40/20

Average speed = 2 m/s

Therefore, the average speed between 0 and 20 seconds is 2 m/s.

it was hot sunny

explanation:

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
