Question

Within 3 hours, the temperature in Oceanside falls by 8 degrees. If the temperature is now at 67 degrees Fahrenheit, what was the temperature 3 hours ago?

Answer 1

Answer: $75^{\circ}F$

Step-by-step explanation:

Given

If the temperature falls by $8^{\circ}$ in 3 hours

Present temperature is $67^{\circ}F$

The difference in temperature i.e.  

$\Rightarrow \text{Previous Temperature}-\text{Present temperature}=8\\\Rightarrow \text{Previous Temperature}=8+67=75^{\circ}F$

Temperature 3 hours ago is $75^{\circ}F$
