Question

On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday to Thursday. What is the temperature on Thursday?

Answer 1

Answer:
`-8^(\circ)C`

Explanation:

Given

The temperature on Tuesday is
`1^(\circ)C`

Temperature drops to
`-2^(\circ)C` on Wednesday

Net drop in temperature
`1-(-2)=3^(\circ)C`

The temperature drops twice from Wednesday to Thursday

`\Delta T=2* 3=6^(\circ)C`

Temperature on Thursday

`\Rightarrow -2-6=-8^(\circ)C`
