Temperature of hot iron rod is 250 drgree Celsius
every minute the temperature ? drop by
10 degree celsius what will be the temperature
of the iron rod after 12 minutes
Step-by-step explanation:
Answer:
Figure out the angle from the two hands to the vertical (12 o’clock) mark and calculate form there.
The minute hand goes 360 degrees in 1 hour or 6 degrees per minute or 60 degrees in 10 minutes.
The hour hand moves 360 degrees in 12 hours, or 30 degrees per hour, or 1/2 degree per minute or 5 degrees in 10 minutes. At 9:00 the hour hand was at 90 degrees, so at 9:10 it is 85 degrees BEFORE vertical.
At 9:10 the minute hand was 60 degrees PAST vertical. So the angle between them is 85+60 = 145 degrees.
