Accepted Solution

A:
Answer:Step-by-step explanation:To solve this you have to find like terms for the fractions:2/5 => 18/45 (amount of power remaining)1/9 ==> 5/45 (power consumption per hour)If we divide 18 by 5 (the amount of power we have left divided by the amount of power consumption we use per hours), we find that the battery will last 3.6 more hours. I hope this helps!
