Answer
2994 minutes.
Work Step by Step
Analyzing the figure on page 241 (Figure 7.25), it can be approximated that at $600^{o}$ it takes roughly 6 minutes to get to the 0.03 mark and roughly 3000 minutes to reach the 0.3 mark. Therefore, the time required can be found by subtracting the two.
$3000 minutes $ $- 6 minutes$ $= 2994 minutes$
