Answer 1

⇒ Correct Question :-

• Neeha observed that the temperature of a substance stared falling drastically after she recorded it as 15°C. What was the temperature after 8 minutes, if it dropped at the rate of 2 degree per minute? ​

⇒ Given :-

• Neeha observed that,

• The temperature of a substance stared falling drastically after she recorded it as 15°C.

⇒ To Find :-

• What was the temperature after 8 minutes, if it dropped at the rate of 2 degree per minute? ​

⇒ Solution :-

• Temperature recorded = 15°C

• Temperature falling at the rate of = 2 degree per minute

• ∴ Temperature after 8 minutes = 15°C - ( 8 x 2)

                                                            = 15°C - 16°C

                                                            = ( 15 - 16)°C

                                                            = -1°C
