Question

If the temperature fell by 1 ½ °C from –2 ½ °C , then what is the current temperature?

• A. -4°C
• B. -1°C
• C. 1°C
• D. 4°C

Answer 1

The correct option is A -4°C

Initial temperature = –2 ½ °C

Temperature drop = 1 ½ °C

Current temperature = –2 ½ °C - 1 ½ °C

= - (2 ½ + 1 ½)°C = -4°C
