Question

Neha swims in a 90 m long pool. She covers 180 m in one min by swimming from one end to the other and
back along the same straight path. Find the total distance travelled, displacement and average speed.

Answer 1

Here , total distance travelled

S = 180 m

Time taken

T = 1min = 60 sec

Average speed = s/t = 180/60 = 3m/s

In swimming from one end to the other and back along the same straight path , displacement = 0

Average velocity :

Displacement / Time = zero

Answer 2

Explanation:

The COVID-19 has resulted in schools shut all across the world. Globally, over 1.2 billion children are out of the classroom.

As a result, education has changed dramatically, with the distinctive rise of e-learning, whereby teaching is undertaken remotely and on digital platforms.

Research suggests that online learning has been shown to increase retention of information, and take less time, meaning the changes coronavirus have caused might be here to stay.

With this sudden shift away from the classroom in many parts of the globe, some are wondering whether the adoption of online learning will continue to persist post-pandemic, and how such a shift would impact the worldwide education market
