A Container contains 80 degree celsius hot water after every 10 minute

1.	A Container contains 80 degree celsius hot water after every 10 minutes the change in temperature is _4 degree celsius after how much time will the temperature of water be 12 degree celsius
Answer» Current Temperature = 80Final Temperature = 12 Total Change in temperature = 80 - 12 = 68 degree celsius Every 10 minutes , 4 degree celsius drop is observed We get , 68 / 4 = 17 Hence, there will be 4 degree celsius drop 17 times That is, 17 x 10 = 170 minutes is the given change -4 degree?then answer is 170 mins or 2 hr 50 mins let after x min temp is 12.then 80-(4x/10)=12 solve it to get the answer.

Answer»

Current Temperature = 80Final Temperature = 12

Total Change in temperature = 80 - 12 = 68 degree celsius

Every 10 minutes , 4 degree celsius drop is observed

We get , 68 / 4 = 17

Hence, there will be 4 degree celsius drop 17 times

That is, 17 x 10 = 170 minutes

is the given change -4 degree?then answer is 170 mins or 2 hr 50 mins

let after x min temp is 12.then 80-(4x/10)=12

solve it to get the answer.
