A) 1.24
B) 1.4
C) 1.15
D) 1.4

Answer 1

To convert 1 hour 24 minutes to decimal hours, divide the minutes (24) by 60 to get 0.4 hours and then add that to the whole hour to get a total of 1.4 hours. The correct option is B.

Step-by-step explanation:

To convert 1 hr 24 mins to decimal hours, you follow these steps:

• Understand that there are 60 minutes in 1 hour.
• Convert minutes to a fraction of an hour by dividing the number of minutes by 60.

24 minutes divided by 60 minutes per hour gives us 0.4 hours.

Therefore, when you add that to the 1 hour, you get 1 hour + 0.4 hours, which equals 1.4 hours. So the correct answer is 1.4.

Note: Do not confuse the decimal representation of time with the minute count. Hence, 1 hr 24 mins is not 1.24 in decimal hours.
