Answer:
B. 6:00
Step-by-step explanation:
There are 60 minutes in one hour.
To calculate 40 minutes after 4:40, separate 40 minutes into two lots of 20 minutes.
⇒ 4:40 + 20 minutes = 5:00
⇒ 5:00 + 20 minutes = 5:20
Therefore, 40 minutes after 4:40 is 5:20
To calculate the time that 5:20 is 40 minutes before, add 40 minutes to 5:20
⇒ 5:20 + 40 minutes = 6:00
Therefore, the solution is option B. 6:00
log x ( 5 × 12 ) = 7
x^7 = 60

Town A starts with 2in and has a rate of accumulation of 6in every 1 hour
Town B starts with 9in and has a rate of accumulation of 3in every 1 hour
If X is number of hours then:
2+ 6X= 9+3X
6x-3x=9-2
3x=7
X=7/3 is about 2 hours
4/3 because 3/3 is 1 and 4/3 is 1 1/3
