Make 2 1/3 improper: 7/3. Make 40 a fraction: 40/1. Multiply 7/3 by the reciprocal of 40/1 (that means the fraction upside down: 40/1=1/40): 7/3x1/40=7/120. 2 1/3 divided by 40 is 7/120 :)
Answer:
a) 3.6 × 10²
Time = distance / speed
So time = 1.08 × 10⁸ / 3 × 10⁸
= 1.08 × 10¹¹ / 3 × 10⁸ ( converted 10⁸ km to meter )
= 1.08 × 10³ / 3
= 0.36 × 10³
. = 3.6 × 10²
Time = 3.6 × 10²
