Question

A weather forecaster says the temperature will be about-5C “give or take” 10 degrees. What is the greatest possible temperature? What is the least possible temperature?

Answer 1

The greatest possible temperature is
`5^(\circ) \mathrm{C}` and least possible temperature is
`-15^(\circ) \mathrm{C}`

Solution:

Given that according to weather forecaster the temperature will be about -5 degree celsius given or take 10 degree”

Need to determine greatest possible temperature and least possible temperature.

Give and take in given statement means a temperature can go up by 10 degrees and can go down by 10 degrees

So greatest possible temperature will be
`-5^(\circ) \mathrm{C}+10^(\circ) \mathrm{C}=5^(\circ) \mathrm{C}`

Least possible temperature will be
`-5^(\circ) \mathrm{C}-10^(\circ) \mathrm{C}=-15^(\circ) \mathrm{C}`

Hence according to weather forecaster, greatest possible temperature =
`5^(\circ) \mathrm{C}` and least possible temperature =
`-15^(\circ) \mathrm{C}`
