please solve this step by step and explain ​

Answer 1

Answer:

2.2 x 10² ms ^-1

Explanation:

3.00 x 10^8 ms^-1 / 1368 x 10^3 s^-1

= 3 x 10^8 ms^-1 / 1368 x 10^3 s^-1

= 3000 x 10^5 ms^-1 / 1368 x 10^3 s^-1

= 2.2 x 10^5 ms^-1/10^3 s^-1

= 2.2 10² ms ^-1

(Note: when we divide 3000/1368 we get 2.19... so we take approx 2.2)

hope it helps...
