The beginning temperature at 2 pm was 49.4 egress Celsius, if the temperature started dropping rate of 0.6 degrees at 2 pm and 47.6 degrees Celsius at 5 pm.
Explanation:
The given is,
Temperature started dropping 0.6 degrees Celsius at 2 pm
Temperature is 47.6 degrees Celsius at 5 pm
Step:1
Difference in hours between 2 pm to 5 pm,
= 5 - 2
= 3 hours
Step:2
Temperature dropping rate = 0.6 degrees Celsius per hour
Temperature dropped at the 3 hours,
= Dropping rate × Hours
= 0.6 × 3
= 1.8 degrees Celsius
Step:3
For the beginning of the temperature,
( we need to add the dropped temperature at the end of the temperature value )
Temperature at 2 pm = Temperature at 5 pm + Dropped Temperature
= 48.6 + 1.8
= 49.4
Temperature at 2 pm = 49.4 degrees Celsius
Result:
The beginning temperature at 2 pm was 49.4 egress Celsius, because the temperature started dropping rate of 0.6 degrees at 2 pm and 47.6 degrees Celsius at 5 pm
