You just need to calculate 8.45% of each of the answer choices. Then choose the one that comes nearest to 2.1 hours.

13. moazzam07

ok calculate meaning?

14. moazzam07

i got D am i correct?

15. kropot72

For example 8.45% of 45 is $\large 45\times0.0845$

16. triciaal

translate the problem 8.45% of battery life = 2.1 hours

17. moazzam07
