Question

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. ​

Answer 1

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.

Answer 2

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
