The correct option is: B.
<u><em>Explanation</em></u>
<u>The general form of growth equation</u> is: , where A = final amount, P = initial amount, r = growth rate in decimal form and t = time duration
Here, the speed of the rocket at the beginning was 5,000 kilometers per hour and at the end will be 25,000 kilometers per hour. The speed increases at a rate of 4.3% per minute.
That means,
Now <u>plugging these values into the above equation</u>, we will get......
So, the equation that could be used to determine the time for the speed of the rocket to reach 25,000 kilometers per hour will be:
