At 5:30 p.m. the temperature of an iron rod is 224 degree Celsius every minute it's the temperature decreased by 7 degree Celsius find the temperature of the road at 5:50 p.m.
Answers
Step-by-step explanation:
At 5:30 p.m. the temperature of an iron rod is 224 degree Celsius every minute it's the temperature decreased by 7 degree Celsius find the temperature of the road at 5:50 p.m.
The temperature of the road at 5:50 p.m is 84 degree Celsius
Given :
At 5:30 p.m. the temperature of an iron rod is 224 degree Celsius
Every minute it's the temperature decreased by 7 degree Celsius
To find :
The temperature of the road at 5:50 p.m.
Solution :
Step 1 of 2 :
Calculate total decrease in temperature
Here it is given that At 5:30 p.m. the temperature of an iron rod is 224 degree Celsius
We have to find the find temperature of the road at 5:50 p.m.
Time duration
= 5:50 p.m. - 5:30 p.m.
= 20 minutes
Every minute it's the temperature decreased by 7 degree Celsius
∴ Total decrease in temperature
= 20 × 7 degree Celsius
= 140 degree Celsius
Step 2 of 2 :
Find the temperature of the road at 5:50 p.m.
The temperature of the road at 5:50 p.m.
= The temperature of the road at 5:50 p.m. + Total decrease in temperature
= 224 degree Celsius - 140 degree Celsius
= 84 degree Celsius
