Asquirrel is traveling at a rate of 12 miles per hour. write the rate in miles per minute

1/5 or 1 mile per 5 minutes

Step-by-step explanation:

if it is 12 mile per hour, change it to a ratio:

12 miles: 1 hour

Change this to minutes:

12 miles : 60 min

To find mile per minute, divide & simplify

12/60 = 1/5

We need to call for x minute
+ Phone Company A charges a monthly fee of $42.50, and $0.02 for each minute talk time. So we have to spend: $42.50+ $0.02x
+ Phone company B charges a monthly fee of $25.00, and $0.09 for each minute of talk time. So we have to spend: $25.00+ $0.09x

We solve for x: $42.50+ $0.02x> $25.00+ $0.09x
or $42.50- $25.00 > $0.09x- $0.02x
and we have $0.07x<$27.50
or x< 27.50:0.07 and x< 393.86

The answer is:
If we have to call much time, at least 394 minutes, we should choose A
If not, choose B
