Battery was charged. when the charging began it was 23% full after 30 minutes of charging the battery was 89% full. how fast was the battery charged? how long did it take the battery to be funny charged?

The battery was charged at a rate of 2.2 % per minute.

It took 35 minutes to fully charge the battery

Step-by-step explanation:

Initial amount of charge = 23%

Charge after 30 minutes = 89%

Percentage of charge gained in 30 minutes = 89-23

                                                                         = 66 %

Charging speed of battery =

=

= 2.2 % per minute

2.2% charge takes 1 minutes

1% charge takes minutes

Initially it was 23% charged so it needs 77% more charge to be fully charged.

So, 77% charge takes minutes    

                         =   minutes

                         = 35 minutes

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
