Question

Fourty mins after 4:40 is fourty mins before…

Answer 1

Answer:

The correct answer is B: 6:00

Step-by-step explanation:

Each hour is an interval of 60 minutes, so first in order to calculate 40 minutes after 4:40, you need to add 20 minutes in order to make 4:40 into 5:00. Then you add the remaining 20 minutes and you'll get that 40 minutes after 4:40 is 5:20. Since we are trying to find the time that 5:20 is 40 minutes before, you must add an additional 40 minutes to that time, which equals 6:00. Therefore, fourty minutes after 4:40 is fourty minutes before 6:00.

Answer 2

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
