Question

in the afternoon the temperature was 52°F. A strong arctic cold front caused the temperature to drop 38 degrees in 4 3/4 hours. If the temperature continues to drop at the same rate, what will the temperature be after 2 hours

Answer 1

Answer: 32 2/19°

Step-by-step explanation:

The decrease in temperature per hour will be calculated thus:

= (52 - 38) / 4¾

= 14°/4¾

= 2 18/19° per hour.

If the temperature continues to drop at the same rate, then the temperature after 2 hours will be:

= 38° - (2 18/19 × 2 hours)

= 38° - 5 17/19°

= 32 2/19°

Therefore, the temperature after 2 hours will be 32 2/19°.
