Final answer:
The number of minutes in any number of hours is found by multiplying the number of hours by 60. For converting seconds to minutes or minutes to hours, one must divide or multiply by 60, respectively.
Step-by-step explanation:
The number of minutes in any number of hours is found by multiplying the number of hours by 60, since there are 60 minutes in one hour. Therefore, the correct choice is 'c) 60 x', where 'x' represents the number of hours. When converting units of time from seconds to minutes or from minutes to hours, you must use division or multiplication depending on whether you are converting to a larger or smaller unit.
Here are a few examples illustrating this concept:
- Converting 3000 seconds to minutes: Divide 3000 seconds by 60 to get 50 minutes.
- Converting 6000 seconds to hours: First convert 6000 seconds to minutes (100 minutes), then divide by 60 to get 1 and 2/3 hours or 1.67 hours approximately.
- Converting 360 minutes to hours: Divide 360 minutes by 60 to get 6 hours.
- Converting 180 minutes to hours: Divide 180 minutes by 60 to get 3 hours.
- Converting 120 seconds to minutes: Divide 120 seconds by 60 to get 2 minutes.
- Converting 4 hours to minutes: Multiply 4 hours by 60 to get 240 minutes.
