Question

A person charges the phone to 100 % battery. If the phone discharges at the rate of 10 % per hour, how long will the phone battery last? Also, write the equation for the same. [x = time, phone charge remaining = y]

Answer 1

Answer:

It will last for 10 hours if discharges at the same rate.

Step By Step Explanation:

The question states that the phone charge is 100.

Now, if it discharges at a rate of 10% per hour then,

Current Charge ÷ Rate of Discharge = Hours It Will Last

100÷10=10

Hence the charge will remain for 10 hours.
