Answer:
28 minutes
Step-by-step explanation:
Dans computer reads 68% of battery left after 1 hour. This means that 1 hour is 68% of the computer's entire battery life.
Let the entire battery life be x (in hours). Hence:
Therefore:
=> x = 1.47 hrs = 1 hr 28 minutes
Hence, the entire battery life is 1 hr 28 minutes.
If 1 hour has elapsed, the remaining time left for his battery to provide power will therefore be:
1 hr 28 minutes - 1 hr = 28 minutes
His battery will provide power for 28 more minutes.
