Answer:
A) 3hrs
Explanation:
Fission is the action of dividing or splitting something into two or more parts.
So, we're going to continuously multiply our answers by 2 until we get 360
10 x 2 = 20 30min
20 x 2 = 40 1hr
40 x 2 = 80 1hr 30min
80 x 2 = 160 2hrs
160 x 2 = 320 2hrs 30min
320 x 2 = 630 3hrs
