Answer to Problem 64E
The number of degrees moved by hour hand of clock in 2 hours 12 minutesare
Explanation of Solution
Given information:
The degrees moved by hour hand of clock in 2 hours 12 minutes.
Calculation:
Consider the provided information that degrees moved by hour hand of clock in 2 hours 12 minutes.
It is known that the degrees moved by hour hand each hour is,
Therefore, the degrees moved by hour hand of clock in 2 hours are,
It is known that 1 hour is equivalent to 60 minutes. So, 1 minute is equivalent to
Therefore, 12 minutes is equivalent to
Therefore, the degrees moved by hour hand of clock in 12 minutes are,
The total degrees moved by hour hand of clock in 2 hours 12 minutes are
Thus, the number of degrees moved by hour hand of clock in 2 hours 12 minutes are
