Answer:
91.30 minutes
Step-by-step explanation:
Assuming that when you start charging the phone it had 0% charge, what you should do is a rule of three.
That is, yes in 21 minutes I charge 23%, how long will it take to charge 100%.
charge time charge percentage.
21 minutes 23%
x minutes 100%
Then it would be:
x = 100 * 21/23 = 91.30
So you would have to wait 91.30 minutes to wait for the full charge.
30 + 0.25m > 40 + 0.10m
0.25m - 0.10m > 40 - 30
0.15m > 10
m > 10/0.15
m > 67 miles.....u would have to drive 68 or more miles for the second company to be less expensive
2 times as much.
