Dans computer reads 68% of battery left after 1 hour. If the rate of using power remains the same, about how much longer will hi
Tanya [424]

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:

\frac{1}{x} * 100 = 68

Therefore:

\frac{100}{x} = 68\\\\x = \frac{100}{68}

=> 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.
