Answer 1

Answer:

a. 2.998 × 10⁸ m/s

b. 23.984 × 10⁸ m

Step-by-step explanation:

a. This form is called standard form

=> Given normal form is transformed to standard form

-----------------------------

b. We know that,

$Speed = \frac{Distance}{time}$

Hence,

$2.998 \times 10^8 = \frac{Distance}{8} \\\\=> Distance = 2.998 \times 10^8 \times 8\\=> Distance = 23.984 \times 10^8 \ m$
