A fast charger can fully charge an android phone in 2 hours. If the phone battery is currently at $26 \%$, how long will it take for the phone to be $100 \%$ charged?
Answer
Final Answer: It will take approximately \(\boxed{1.48}\) hours for the phone to be fully charged.
Step 1 ：We know that the charger can fully charge the phone in 2 hours. This means that it charges the phone at a rate of \(100 \%\) per 2 hours, or \(50 \%\) per hour.
Step 2 ：If the phone is currently at \(26 \%\), it needs to be charged an additional \(100 \% - 26 \% = 74 \%\).
Step 3 ：We can find the time it takes to charge this amount by dividing the amount to be charged by the rate of charging.
Step 4 ：\(\frac{74}{50} = 1.48\)
Step 5 ：Final Answer: It will take approximately \(\boxed{1.48}\) hours for the phone to be fully charged.
