the outside temperature at 4:00 p.m. was 8 degrees celsius. the temperature decreased 2.5 °c each hour until 10:00 p.m. what was the temperature at 10:00 p.m.?

Answer

Explicación:

Paso 1: Calcular el número de horas transcurridas

Entre 4:00 p.m. y 10:00 p.m. han pasado 10 - 4=6 horas.

Paso 2: Calcular la reducción total de temperatura

Como la temperatura desciende 2.5°C cada hora y han pasado 6 horas, la reducción total es 2.5×6 = 15°C.

Paso 3: Calcular la temperatura a las 10:00 p.m.

La temperatura inicial a las 4:00 p.m. era 8°C. Restando la reducción total, 8−15=- 7°C.

Respuesta:

  • 7°C
