A cold front

At 1:00 PM, the temperature was at 46 degrees. Then, a cold front moved in and decreased the temperature 12 degrees per hour. The temperature at 6:00 PM = _____ degrees.

Result

t =  -14 °F

Solution:

T=61=5 h  t=4612 T=4612 5=14=14FT = 6 - 1 = 5 \ h \ \\ \ \\ t = 46 - 12 \cdot \ T = 46 - 12 \cdot \ 5 = -14 = -14 ^\circ F



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
